COMFORTER & CARERS
and Others Exposed Via the Medical Exposure of Another
Person
Who are COMFORTER AND CARERS?
"COMFORTERS AND CARERS", under IRR991 are defined as "individuals who (other than as
part of their profession2) knowingly and willingly incur an exposure to ionising radiation in the
support or comfort of another person who is undergoing, or has undergone a medical exposure"
COMFORTER AND CARERS may include members of the public who, for example
visit patients in hospital after those patients have been administed with
radiopharmaceuticals or are undergoing brachytherapy
offer support for those patients at home who have undergone certain nuclear
medicine procedures, or had sealed sources permanently implanted
(in some cases) offer support to a young child or disabled person while that person is
X-rayed
and are likely to receive more than the public dose limit of 1 mSv a year resulting from
direct radiation or contamination during the comfort and support they offer.
If they are unlikely to receive more than 1 mSv a year then they need not be classified
as COMFORTER AND CARERS under IRR99.
IRR99 also allows a separate dose limit for persons who may be exposed to radiation
resulting from the medical exposure of another. This limit is 5 mSv in 5 years. This limit is
1 The Ionising Radiations Regulations 1999
Comforters and Carers
• e.g. parent holding a child being X-rayed
• not a nurse, care assistant, etc.
• if < 1 mSv public dose limit, not “C&C”
• 5 mSv dose constraint
• if pregnant 1 mSv dose constraint
• must be aware of the risk.
Scatter Dosee.g. Lat. Lumbar spine
• No lead apron: 0.6 mGy @ 30 cm
• With 0.35 mm apron: 0.06 mGy @ 30 cm
• Public dose limit = 1 mSv 17 patients
• C&C constraint = 5 mSv 83 patients
• Staff limit = 6 mSv 100 patients.
Doses Relative to Lum. Sp.
• Chest: x 0.02
• Skull: x 0.04
• Thoracic spine, pelvis: x 0.5
• Abdomen: x 0.8
• IVU: x 1.5
• Ba. Enema: x 4.1
• CT abdomen: x 5.9.

Responsibility: Radiographer in charge of the procedure. Appropriate checks: a) Name
b) Date of birthc) Address if applicabled) Wristbands on inpatientse) LMP checks to comply with 28 day rule on
women between the ages of 12 and 50f) See special circumstances
FLUOROSCOPY PROCEDURES
All outpatients and inpatients must identify themselves before exposure toionising radiation
Responsibility: Radiographer in charge of the fluoroscopy session. Appropriate checks: a) Name
b) Date of birthc) Address if applicabled) Wristbands on inpatientse) LMP checks to comply with 28 day rule on
women between the ages 12 - 50f) see special ciircumstances
SPECIAL CIRCUMSTANCES
Responsibility: Radiographer in charge of the examination.
PAEDIATRIC PATIENTS WITH RELATIVE OR CARER The appropriate identity checks should be done with the child if they are
able to answer for themselves. If this is not the case the relative or carershould answer for the child
PATIENTS WITH LEARNING DIFFICULTIES If the patient is unable to identify themselves verbally then identification
must be sought from an escort or relative if present. Otherwise the referringdepartment/Doctor must be contacted
PATIENTS WITH LANGUAGE DIFFICULTIES Escort or relative accompanying can be used to verify patient identification.
Otherwise use hospital interpreters
PATIENTS WITH HEARING OR SENSORY IMPAIRMENT An escort or relative can be used to verify patient identification if present. Otherwise use writing or sign language
HELPERS/STUDENT RADIOGRAPHERS CHECKING PATIENTIDENTIFICATION It is the radiographer’s responsibility to ensure that the correct patient is
irradiated at all times. Student’s can check patient’s identification by theabove methods

REFERRERS, PRACTITIONERS & OPERATORS
Procedure to Identify Individuals Entitled to Act as Referrer, Practitioner or
Operator
- DIAGNOSTIC PROCEDURES1 -
(i) REFERRERS - Medically Qualified
Clinically justified referrals for diagnostic procedures using ionising radiation will be
accepted from registered medical and dental practitioners. Referrals will also be
accepted from provisionally registered practitioners working under the direct supervision
of a fully registered colleague.
It is not feasible for the Trust to maintain up to date lists of all medical practitioners in
hospitals and general practice. All requests arising from such will be assumed to
originate with a qualified medical or dental practitioner and to be signed by the
responsible clinician. The Trust will, as far as is possible, make it clear to referrers that
these are the expectations and any departure from these will be a violation of the
Regulations2.
With the introduction of order coms, the person requesting the examination will have
been delegated a password to enable them to request. This will have been post
verification by the Department performing the medical exposure and subject to the
referrer working to set referral protocols. This system will be reviewed yearly.
1 Including interventional radiology2 Ionising Radiation (Medical Exposures) Regulations 2000 (IRMER)
(iii) PRACTITIONERS
This is inclusive of all grades of Radiologist within their area of expertise. Other
appropriately qualified and trained members of staff may act as practitioners as agreed
by the Department performing the medical exposure, in discussion with the Clinical Lead
and within a defined range of procedures.
If any doubt exists as to roles / responsibilities and the patient would be put at risk if the
procedure did not continue, then the examination should be performed. All details must
be recorded and the situation reviewed / assessed to avoid a future reoccurrence.
(iv) OPERATORS
e.g. radiologists, radiographers, appropriately supervised trainees/students, medical
physicists, medical technologists, dark room technicians, and X-ray engineers.
Individuals will only be allowed to act as operators in those areas for which they have
received appropriate training.
Occasionally, staff with no radiological background may need to act as operators, e.g.
clinicians performing clinical procedures under fluoroscopic guidance. Such staff will be
required to undergo such training as agreed by the appropriate professional organisation
and Royal Colleges. The number of persons requiring such training, should be kept to a
minimum by ensuring that, whenever possible a qualified radiographer acts as operator.
- THERAPEUTIC PROCEDURES -
(v) REFERRERS - Medically Qualified
As for diagnostic procedures.
(vi) REFERRERS - Non-medically Qualified
Referrers(requests medical exposure)
• registered medical and dental practitioners (order coms password required)
• non-medical referrers must be approved for specific requests by Radiology Dept.
Practitioners(justifies exposures)
• radiologists
• others as approved by Dept.
Operators(performs practical aspects)
e.g.• radiologists, • radiographers, • appropriately supervised trainees/students, • medical physicists, • medical technologists, • dark room technicians, • X-ray engineers• authorise exposure under a practitioner.
Medico-legal Exposures
Hull & East Yorkshire Hospitals Radiation Protection Service
RADIATION PROTECTION
POLICY AND PROCEDURES
NUMBER : 21
MEDICO-LEGAL EXPOSURES
Procedure to Observed in Case of Medico-Legal Exposures
Medico-legal exposures are those taken for insurance or legal purposes where there is not expected
to be a direct health benefit to the patient.
When justifying the procedure the practitioner must take any non-medical benefits to the patient into
account. Medico-legal exposures will only be undertaken with the consent of the patient.
For such requests, the cards must be reviewed by a Radiologist / discussed with the Department
performing the exposure.
The practitioner and operator should pay special attention ti the need to keep doses arising from
medio-legal exposures as low as reasonably practicable.
Quality Assurance

POLICY AND PROCEDURES
NUMBER : 20
QUALITY ASSURANCE
It is a requirement, both under the Ionising Radiation Regulations 1999 and IRMER 2000, that
Quality Assurance Programs be implemented and that the employer shall have adequate procedures
in place to ensure that they are carried out. This also implies regular review of policy and
procedure(s) method.
1. Equipment
a. A regular program of tests shall be carried out and recorded by the operators. The
content, frequency and acceptable range of results will be in line with accepted national
practice (currently IPEM 77) as defined by the Radiology Manager and RPA or their
representatives.
b. More comprehensive and independent tests will be carried out annually by the Radiation
Protection Service with reports submitted to the Radiology Manager.
c. Acceptance surveys will be carried out for all new equipment and following major
repair/replacement which may affect patient dose or image quality.
2. Standard Operating Procedures
a. It is the responsibility of the Radiation Protection Supervisor and other senior staff to
ensure that agreed working practices are maintained and any discrepancy reported to the
Service Manager.
b. Audit of compliance will be carried out on an annual basis by the Radiation Protection
Service.
3. Review
The Service Manager, Lead Clinician and Radiation Protection Advisor will meet regularly
(and at least annually) to review results of Quality Assurance Audit. Recommendations will
be given to the Clinical Risk committee and Divisional Management.

Quality Assurance
• Equipment
• - regular by operators
• - annually by Rad. Pro. Service
• acceptance tests for new or repairs that affect dose
• Procedures - annual audit by Rad Pro Service.
Incidents•Any untoward occurrence which may result in excess radiation to staff or patients must be referred to the Radiation Protection Supervisor and the Radiation Protection Adviser, who will estimate the dose and liase with management, HSE, DoH, HMIP, etc. as appropriate
•Suspect equipment must be withdrawn from service and labelled according.
Patient Doses Much Greater Than Intended
• x 20 - extremities, skull, chest, etc.
• x 10 - lumbar spine, abdomen, pelvis, mammography and other examinations not referred to elsewhere,
• x 3 - fluoroscopy, digital radiography, C.T
Investigation
establishing what happened
identifying the failure
deciding on remedial action to minimise the chance of a similar failure
