The entry that closes the nuclear gauges group
One point before anything else. Meeting the conditions in the Decision is what you can prepare for. Whether a licence is granted, and when, is a decision of the competent authority alone, and nothing in this explanation and nothing in any course is a commitment that a licence will be issued or that it will be issued within a given period. What this article does is set out the condition as the instrument states it and point to the training that bears on it.
Item 10 of the industrial applications in the schedule attached to Decision 4 of 2007 is the last of the four nuclear gauges entries and the least familiar of them. The three before it license the people who supervise gauges, carry gauges and read fixed gauges. This one licenses the person who operates the devices with which gauges are calibrated, and it is an entry a plant usually meets for the first time when a gauge has drifted and the question of who may work on the calibration arrangement arises.
Two things need saying at the start of this article, and both of them are limits rather than readings. The first is about us. The Institute does not carry out instrument calibration. That is stated below among the limits of what the Institute does, and it bears repeating at the top of an article about a calibration licence: what we do here is explain the condition in the item and point to the training the item names, and the training the item names in the radiation protection limb is a course we deliver. We do not calibrate gauges, we do not test equipment, and we do not analyse samples.
The second is about the text. One word in the academic condition of item 10 is in doubt in the copy of the schedule held in our library, and the word is doubtful in the original rather than in our transcription of it. We quote the condition exactly as the copy carries it, we say where the doubt is, and we do not correct it and do not build a reading on either possibility. An article about this entry that did not say so would be offering a condition as settled when the wording of it is not, and in this series what is quoted is what is relied on and what is in doubt is flagged.
The four conditions
Item 10 opens with the formula that opens each of the four gauges entries: the following conditions must be present in the person who is granted a licence to work as an operator of devices for calibrating nuclear gauges. Notice that the function the formula names is the operation of devices for calibrating gauges, and not the calibration itself and not the gauges. The heading of the item is written the same way: operator of devices for calibrating nuclear gauges. The heading and the formula are written alike in three of the four gauges entries, and this is one of the three. The exception is item 9, the fixed gauge entry above it.
Then come four conditions. The academic condition is that he hold a diploma in a branch of engineering or, in the word the printed copy carries, work, two years after general secondary, at minimum. The first training condition is that he pass a training course in the field of nuclear gauges. The second is that he pass a training course in radiation protection in industrial applications from an approved centre. And the fourth is that he pass the prescribed medical examination. There is no experience condition in the item. The prescribed medical examination is a fitness condition for the licence. It is not a protective measure, it does not stand in for any course the item names, and it does not stand in for anything in operational protection.
Three observations before the doubtful word. The academic level is a diploma, and this condition carries a parenthesis of its own fixing a duration, two years after general secondary, together with at minimum. The parenthesis settles a length and nothing else: the nature of the qualification, the awarding body and how equivalence is treated are not addressed in the item, and they are for the competent authority. The nuclear gauges course is named with nothing said about where it is to come from, exactly as in the supervisor entry at item 7, and the protection course in the same item is described as coming from an approved centre. And the absence of an experience condition puts this entry beside the fixed gauge entry at item 9 and apart from items 7 and 8, each of which names a number of years.
The word that is in doubt
The academic condition names a diploma in a branch of engineering or a second field, and in the copy of the schedule held in our library that second field is the word work. Items 4 and 7, the two entries this article reads alongside item 10, name a second field in the same position as sciences, and the two words are closely similar in writing. Item 7 above, for the gauge supervisor, reads that he hold the first university degree in engineering or sciences. So the sense of the item and the wording of its neighbours point one way, and the printed text in front of us says the other.
What we do with that is the whole method of this series in one place, so it is worth stating plainly. We quote the condition as the copy carries it and we do not silently correct it. We record that the word is in doubt. And we do not build any reading on either possibility: we do not tell you that a diploma in sciences satisfies the condition, and we do not tell you that one does not, and we do not tell you what a diploma in the other field would do either. A transcription note is an admission that we do not know; resolving it would be a claim that we do, and we do not.
The practical consequence is narrow and it is actionable. If the qualification your candidate holds is a diploma in a branch of engineering, the doubtful word does not affect him: the first field in the condition is engineering in both readings, and his file is read against the rest of the condition, which is the level and the two years after general secondary and the phrase at minimum. If his diploma is in anything else, the doubtful word is the whole of his case, and that is the point at which the enquiry has to be made before the file is built rather than after it is returned.
So the step is to read the condition on the page image of the Official Gazette, or to ask the Ministry for the wording in force, naming the diploma your candidate holds and quoting the condition as it stands in the copy you have, and to keep the reply. That is a short letter and it settles a question that no amount of reasoning about the sense of the item can settle, because the sense of an instrument is not its text.
Item 10 against item 7, the two entries that leave the course undescribed
Item 10 and item 7 are the two entries in the gauges group that name the nuclear gauges course and say nothing about where it is to come from, while both of them describe the protection course in the same item as coming from an approved centre. Reading the two together is useful because one of them carries an experience condition and the other does not, and because their academic conditions are written at different levels, which this article records without ranking them. The table compares them. It is a reading of items 7 and 10 of the industrial applications, both quoted in full on the Arabic version of these four articles, and nothing is added to it.
Items 7 and 10 compared
| Condition | Supervisor, item 7 | Calibration devices, item 10 |
|---|---|---|
| Function named in the formula | To work as a nuclear gauge supervisor | To work as an operator of devices for calibrating nuclear gauges |
| Academic condition | First university degree in engineering or sciences, with the phrase at minimum not used | Diploma in a branch of engineering or a second field whose word in the copy we hold is in doubt, two years after general secondary, at minimum |
| Nuclear gauges course | Required, with nothing said about its source | Required, with nothing said about its source |
| Industrial radiation protection course | Required, from an approved centre | Required, from an approved centre |
| Experience | Practical, not less than two years, with no field named | No experience condition in the item |
| Prescribed medical examination | Required | Required |
| Heading and opening formula written alike | Yes | Yes |
What to settle before the file is assembled
Below is the order we use when a client asks us to look at a file on this entry. It is the Institute's own working practice, and the items set out in this explanation impose no form of file. The order is different from the other three gauges entries in one respect: here the first step is about the text of the condition rather than about the candidate.
Preparing a calibration devices file
Settle the doubtful word first, but only if it bears on your candidate
- If his diploma is in a branch of engineering the question does not arise, because that field is in the condition on either reading, and the file is read against the level and the two years after general secondary instead.
- If it is in anything else, write the enquiry before the file is built: quote the condition as your copy carries it, name his diploma, and ask for the wording in force.
Buy the two courses as two courses
- The gauges condition and the protection condition are two of the four conditions of item 10, with different subjects, and a single combined certificate answers one and leaves the other without evidence. On an entry with four conditions that produces a file evidencing three while reading as complete.
- The protection course here is the one the item describes as coming from an approved centre, so its provider is the one capable of being questioned on the words of the item, and the gauges course is the one the item leaves undescribed.
Do not read the absence of an experience condition as a licence to assign work
- The item contains no experience condition, so no period of prior service has to be evidenced for this licence. The protection duties the Law, the Regulation and the conditions of the facility licence place on a licensee are unaffected, and a calibration arrangement is not a setting in which a person works out what the equipment does.
Be clear with your provider about what calibration work you are buying
- The Institute does not carry out instrument calibration, does not test equipment and does not analyse samples, so a calibration service is bought from a provider that offers it and a licence file is a separate matter from that purchase.
- What the Institute does here is the radiation protection training the item names, the file review against the four conditions, and the drafting of the enquiry about the doubtful word and the prescribed medical examination.
Questions we are asked about this item
Does a diploma in sciences satisfy the academic condition of item 10?
We will not answer that, and the reason is in the text rather than in caution. The second field named in the condition, in the copy we hold, is a word closely similar in writing to the word items 4 and 7 use in the same position, and the sense of the item points one way while the printed text says the other. We quote the condition as the copy carries it, we record that the word is in doubt, and we do not resolve it. If your candidate's diploma is in a branch of engineering the question does not arise. If it is not, ask the Ministry for the wording in force and keep the reply.
Does this entry cover the person who sends gauges away for calibration?
The formula licenses working as an operator of devices for calibrating nuclear gauges, so the function it names is the operation of those devices. Whether a particular arrangement on your site involves operating them, and whether sending a gauge to a provider puts anyone at your end inside the function, are questions for the Ministry. We flag only that the entry names devices and their operation, and that a role described in a plant procedure is not the same thing as an entry in this schedule.
Does the Institute calibrate gauges, or certify a calibration?
No to both. The Institute does training and consulting. Field radiation surveys are carried out through specialist partners, and the Institute does not carry out laboratory analysis, instrument calibration or equipment testing. What the Institute delivers that bears on this entry is the radiation protection course in industrial applications that the item names as its second training condition, together with the file review and enquiry drafting described below.
Where should the nuclear gauges course for this entry come from?
The condition names the course and says nothing at all about its source, where the protection condition in the same item describes its source as from an approved centre. The supervisor entry at item 7 is written the same way, and the portable gauge entry at item 8 writes the same course subject with that description present. We record the differences across the group and we do not read either a permission or a restriction into the silence. Name your course and your provider, quote the condition, and ask in writing before the course is booked.
Our calibration arrangement is not described by any of the four entries. What then?
The third part of the schedule provides for that: licence applications for the specialities that are not stated in these instructions are referred to the Radiation Protection Committee to decide on them, and the Committee shall be guided by international instructions and standards, in particular those issued by the International Atomic Energy Agency. So the route is referral, the decision is the Committee's, and the guidance it is directed to is named in the provision. The provision does not give you the alternative of applying the conditions of the nearest listed entry to yourself, and in our practice that assumption is the error we see: in this group it usually means taking the fixed gauge entry to govern because it asks for least.
A technical note: the licence is not the protection
A technical note, and it is the most important passage on this page. The conditions in this Decision are licensing conditions, not site work instructions. Meeting them, and any licence that may follow, replaces nothing in operational protection, and no course makes anyone safe by itself. One rule governs every judgement about where a source is: it is settled by measurement, never by inference.
The measurement is made by the licensee, through a person qualified to make it, and the instrument has to respond to the radiation actually present and at the energies present. For a gamma source that means a gamma survey meter within its calibration validity and response-checked before work starts. Where the equipment also carries a source for measuring moisture content, the instrument has to respond to neutrons as well, because a gamma-only meter can read clean standing beside an unshielded neutron source.
What does not count is an inference. Not a mechanical indicator, not a position switch, not a painted mark, and not the fact that the work went as planned. And if the measurement does not establish that the source is shielded, the work stops where it is, no one approaches the equipment, and the licensee acts on his own emergency arrangements and notifies the Ministry. These are obligations on the licensee under the Law, the Regulation and the conditions of his own licence, and their place is not this Decision.
This entry is the one in the gauges group whose work has the highest dose potential, and the technical note has to say so. A calibration arrangement deliberately exposes a reference source in a defined geometry, and while a calibration run is in progress there is no shutter-closed resting state to fall back on: the protection comes from the geometry, the distance, the shielding and the controlled access of the arrangement, and from the fact that no one is inside it while the source is exposed. So the measurement is made before entry and not after it, with an instrument that responds to the radiation that arrangement actually produces, and the source is treated as exposed until a measurement says it is not. A reference source is also an accountable item in the records kept by the licensee, and a calibration run that ends with any doubt about where that source is ends with the work stopped, no one approaching the arrangement, and the licensee acting on his emergency arrangements and notifying the Ministry. The Institute does not carry out calibration and nothing in this note is a procedure for one: these are obligations on the licensee, and his arrangement is written by whoever is competent to write it.
How the Institute can help
Two findings recur on files for this entry. The first is a diploma offered against the academic condition without anyone having noticed that the second field named in the condition is a word in doubt in the printed copy, so the file rests on a reading of the text that has never been put to the authority. The second is one combined certificate offered against both training conditions, which on an entry with four conditions leaves a file evidencing three while reading as complete.
The Institute delivers radiation protection training for industrial applications, reviews a licence file against item 10 condition by condition, drafts the enquiry to the Ministry on the wording in force of the academic condition, on the standing of a named gauges course at a named provider and on the prescribed medical examination, and advises on which of the four gauges entries applies to each role on a site. The nuclear gauges training the Decision names is a separate qualification obtained from a provider that offers it, and the Institute does not issue it. What the Institute delivers is the radiation protection course in industrial applications that all four of these items name as a subject; whether a particular course at a particular centre satisfies the approved-centre limb of the condition is for the Ministry to say.
Scope of what the Institute does: training and consulting. Field radiation surveys are carried out through specialist partners. The Institute does not carry out laboratory analysis, instrument calibration or equipment testing.
A note on the source of a course in these four items. All four of them ask for the radiation protection course in industrial applications to come from a centre that the Decision describes with an Arabic word this explanation renders as approved. The nuclear gauges course is treated differently between the items: in the portable gauge entry it is to come from a centre described with that same word, and in the supervisor entry and the calibration devices entry the condition names the course and says nothing at all about where it is to come from. The items set out in this explanation do not define the term, do not say who gives that approval, and do not say whether it is a general status or given for a particular course. Where the description does appear, it qualifies the provider of the training and no other party. The English word is a rendering chosen for this explanation and is not a term of art: our practical reading is to ask in the Arabic wording of the item, naming the specific course and the specific provider, and to keep the answer in writing, because what the instrument leaves open the authority settles. The Institute is a licensed training provider and describes itself that way and no other way.
A note on one word in the text. The academic condition of the calibration devices entry, in the copy of the schedule held in our library, names a diploma in a branch of engineering or a second field, and in that copy the word for that second field is the word for work rather than the word for sciences. The two words are closely similar in writing. The sense of the item and the wording of the parallel entries point one way, and the printed text says the other. We therefore quote the condition exactly as the copy carries it, we record that the word is in question, and we do not correct it in the quotation and do not build any reading on either possibility. Anyone whose own qualification turns on that word should read the condition on the page image of the Official Gazette, or ask the Ministry for the wording in force, before relying on it.
A note on the authority named in the text. The word the Decision uses for the authority is the Council. It is the word of a 2007 instrument whose preamble refers to the Executive Regulation issued by decision of the President of the Supreme Council for the Environment and Natural Reserves, number 4 of 2003. The body that word names no longer exists. Competence today sits with the Ministry of Environment and Climate Change, and the unit concerned is named in the organisational decisions as the Radiation Protection Department. The word Council is kept only where this explanation renders what the instrument itself says, because that is the instrument's own word; in the Institute's own advice it is written as the Ministry. Read Council as the Ministry throughout.
This explanation is published for awareness by the radiation protection team at ALDuha Institute for Training and Environmental Consulting. The English text is an explanation, not a certified translation: the Arabic text published in the Official Gazette governs in case of any difference, and the official Arabic wording of every condition discussed here is quoted in full on the Arabic version of this article. This explanation is introductory. It is not a legal opinion, it does not replace the conditions of your own licence, and it does not replace review by the regulator. Last updated 7 October 2026.
