Three articles about people who are not staff and not patients
A hospital counts its radiation workers and it counts its patients. The people it usually does not count are the ones these three articles are about: the son who drove his mother to her scan and is sitting outside the room, the maintenance technician crossing a corridor, the supplier's engineer being shown around, the family in the house nearest the fence.
The three fit together as a system, and they answer three different questions. Article 56 asks how the licensee organises the protection of the public at all, and gives seven requirements. Article 55 asks what happens to the people who come with a patient, and gives an answer that is often misread. Article 60 asks what happens when somebody actually walks into a controlled area, and gives two conditions.
Article 56: seven requirements, and the idea that runs through them
Article 56 is headed Requirements for organising the protection of the public, and it opens by binding the licensee to comply with what follows. Seven items follow. The first OCR pass of the page showed only five, which is worth mentioning because a facility working from a damaged copy would be two requirements short without knowing it.
Item 2 is the one that introduces a concept the rest of the chapter depends on: taking the measures that ensure optimal protection and the restriction of normal exposure of the critical group. The critical group is not a legal fiction. It is the small group of members of the public who, because of where they live, what they eat or how they travel, receive the highest dose from the facility. The logic is simple and powerful: protect them adequately and everyone else is protected by definition.
Identifying that group is the work most sites skip. It is not always the nearest house. It may be the children at a school on the prevailing downwind side, or the family that grows vegetables beside a discharge point. Item 2 does not say how to find them, but items 3 and 4 give the tools.
Item 3 is the longest of the seven and the most often quoted in part. It requires the measures needed to achieve the security of the sources so that the possibility of public exposures can be monitored, and the security of the facilities, the equipment and the services suitable and sufficient for the protection of the public - and then adds the proportionality test: their nature and extent must be proportionate to the magnitude of the exposure and its likelihood.
Magnitude and likelihood together. That pairing is the whole of risk assessment compressed into one clause, and it is what allows a small clinic and a large industrial site to be judged by the same article without being asked for the same measures.
The seven requirements of Article 56
Organising and measuring
- 1. Procedures and organisational arrangements for protection and safety regarding public exposure.
- 2. Measures ensuring optimal protection and the restriction of normal exposure of the critical group.
- 4. Monitoring equipment and suitable surveillance programmes to assess public exposure.
Securing what can reach people
- 3. Security of the sources so that the possibility of public exposure can be monitored, and of the facilities, equipment and services - proportionate to the magnitude of the exposure and its likelihood.
People, records and the bad day
- 5. Suitable training for the staff who carry out functions connected with the protection of the public.
- 6. Keeping adequate surveillance and monitoring records.
- 7. Emergency plans and procedures.
Article 55: the one about patients' companions, and the way it is misread
Article 55 is headed Visitors of patients, and it is a single sentence. The public dose limits do not apply to the persons who accompany or visit patients, and the dose received by any of them is restricted by the limits the Committee sets.
Half of that sentence gets quoted and the other half gets dropped. Read it whole: the article moves these people from one set of limits to another. It does not release them. The public limit does not apply - and a limit set by the Committee for this purpose does. Different limits, not no limits.
The reason for the article is sound. A parent holding a frightened child still during an X-ray, a spouse staying with a patient who has received radiopharmaceuticals, a son visiting a relative after brachytherapy - these are voluntary, informed, and they carry a benefit the public limit was never designed to weigh. Holding them to the limit meant for an uninvolved passer-by would force hospitals to refuse care that families need.
What a department has to do with this article is concrete. Know the Committee's current limits for this category and hold them in writing. Decide in advance who may act as a companion and who may not - the article's protection does not extend to someone who happens to be in the room. Brief them, because a companion who does not know why she is standing where she is standing will move. And where the exposure could be significant, record it.
Article 60: what has to happen before somebody walks in
Article 60 is headed Visitors to controlled areas and supervised areas, and it treats the two kinds of area differently - exactly as Article 26 did when it created them.
For a controlled area it sets two conditions, and neither is a formality. The visit must be in the company of a person knowledgeable in the protection and safety measures. And sufficient information and instructions must be provided to visitors before they enter any controlled area.
Before they enter. A briefing given inside the area, or a form signed on the way out, does not meet the wording. And the escort must be knowledgeable in protection and safety - not merely an employee with a badge who knows the way to the room.
Then the purpose, and it is the same two-sided purpose as item 5 of Article 53: to ensure suitable protection is provided for them and for the other individuals who may be affected by their conduct. The visitor is a risk to himself and a risk to everyone around him, and the article says both in one breath.
For supervised areas the burden is lighter, matching the lighter regime Article 26 set for them: the entry of visitors must be monitored appropriately, and suitable signs put up in these areas. Monitored - not escorted. Signs - not briefings. The difference between the two regimes is the difference between knowing who went in and walking in with them.
Visitors: what each kind of area requires
| Requirement | Controlled area | Supervised area |
|---|---|---|
| Escort | Required - a person knowledgeable in protection and safety measures | Not required |
| Briefing | Sufficient information and instructions, before entry | Not required by this article |
| Entry control | Implied by the escort requirement, and by Article 26 | Entry monitored appropriately |
| Signs | Approved warning signs under Article 26 | Suitable signs in these areas |
Questions these articles get asked
Does Article 55 mean a patient's family has no dose limit at all?
No, and this is the most common misreading of the article. The sentence has two halves. The first says the public dose limits do not apply to them. The second says their dose is restricted by the limits the Committee sets. They move from one limit to another. Ask the competent authority for the current figures for this category and keep them in writing.
Who counts as the critical group for our facility?
The members of the public who receive the highest dose from your operation, because of where they live, what they consume or how they move. It is not automatically the nearest building. Item 4 of Article 56 gives the means to find out - monitoring equipment and surveillance programmes to assess public exposure - and item 2 is the reason to bother: protect that group and the rest of the public is protected with them.
Can we let a supplier's engineer into a controlled area on his own if he is qualified?
Article 60 requires the visit to be accompanied by a person knowledgeable in the protection and safety measures, and does not offer an exemption for a visitor's own qualifications. The other route is to stop treating him as a visitor: a person who works in a controlled area and may be occupationally exposed belongs in the occupational regime, with the monitoring and records that come with it. One of the two, decided before he arrives.
Is a sign at the door enough for a supervised area?
It is half of what Article 60 asks. The article requires suitable signs in these areas, and also that the entry of visitors be monitored appropriately. A sign with nobody knowing who walked past it satisfies one limb and leaves the other empty. Monitoring here does not mean a guard - a log, a badge reader or a reception record can carry it.
We are a small clinic. Do all seven items of Article 56 really apply to us?
The seven apply; their size does not. Item 3 builds proportionality into the article itself - the nature and extent of the measures must be proportionate to the magnitude of the exposure and its likelihood. So a small clinic writes a short emergency procedure rather than none, trains the two people who need it rather than nobody, and keeps a thin monitoring record rather than an empty drawer.
How the Institute can help
These three articles are where public protection stops being a policy and starts being a corridor, a doorway and a person standing beside a visitor. Most of the gap we find in reviews is here: the areas are classified correctly and nobody has written down what happens when somebody who is not staff walks toward them.
Radiation Protection Officer training covering the public exposure chapter, awareness sessions for reception, security and maintenance staff who meet visitors first, help in drafting the visitor briefing and the companion rules for the medical sector, and a documentation review against the seven items of Article 56.
Scope of what the Institute does: training and consulting. Field radiation surveys are carried out through specialist partners working in the field. The Institute does not carry out laboratory analysis, instrument calibration or equipment testing.
