1Radiation Protection Legislation Stephen McCallum
2Radiation Legislation The aim of legislation is to protect, individuals, populations and the environment from adverse affects of ionising radiation.
3Ionising Radiation Regulations 1999 Know as IRR99 - made under the Health and Safety at Work Act Enforcement agency is the Health and Safety Executive (HSE)Controls occupational exposures to workers and exposures to the public as a result of the use of ionising radiation in the work place
4Radioactive Substances Act 1993 RSA93, Enforcement agency is the Environment Agency (EA) in England & Wales and Scottish Environmental Protection Agency (SEPA) in ScotlandSets out regulatory frame work for the keeping of radioactive sources and the disposal of radioactive waste

6IRR99 Employer responsibility Every radiation employer shall, in relation to any work with ionising radiation that he undertakes, take all necessary steps to restrict so far as is reasonably practicable the extent to which his employees and other persons are exposed to ionising radiation
8IRR99 – Classified workers A worker must be Classified if they are likely to receive a whole body dose of more than 6mSv per year or more than 3/10 of any relevant dose limit.Classified workers must under a yearly medical by an doctor appointed by the employer.Issued with a pass book detailing their dose record.Are able to enter controlled areasPersonal Radiation doses must be monitored
9IRR99 – Non Classified workers Classification not required for doses up to 3/10 of relevant dose limit i.e. 6mSv for body dose.Only able to enter controlled area under a system of work drawn up by the employer. System of work normally part of the local rulesPersonal Radiation dose often monitored to show that classification not required
10IRR99 – duties of employer Carry out prior risk assessments before work commencesThis is one of the key elements of the legislation. From the risk assessment the employer should be able to determine the measures required to control and limit doses to staff and the public.
11IRR99 – duties of employer Designation of areasControlled areas under IRR99 should be set up where a person is likely to receive an effective whole body dose of more than 6mSv per year or where there is significant risk of spreading contamination outside the work area.
12Controlled areasMust be under the control of the employerMust be physically demarcatedMust have suitable signageLocal rules should be drawn upRadiation Protection Supervisor appointedEnvironmental and personal monitoring should take place
13Supervised areasAny area where the conditions need to be kept under reviewAny person is likely to receive an effective dose >1mSv/y or > than 1/10 of any other dose limit.It does not automatically follow that outside every controlled area there will be a supervised area.
14IRR99 – duties of employer Draw up local rulesRequired for every controlled area and normally every supervised areaContain a key set of working instructions designed to restrict exposure.Contingency plans if things go wrong.Systems of work for non classified workers.Must take steps to ensure rules or observed an brought to the attention of effected workers
15IRR99 – duties of employer Special consideration for pregnant and breast feeding workersOnce notified must ensure the equivalent dose to the foetus is unlikely to exceed 1mSv during the remainder of the pregnancy;For breastfeeding mothers restrictions in place to prevent significant bodily contamination of that employee
16IRR99 – duties of employer Appointment of Radiation Protection SupervisorResponsible for ensuring that the Local rules are adhered to and for supervising the arrangements.Know and understand the requirements of the relevant regulations and local rules.Command sufficient authority to allow them to supervise the work.Understand the necessary precautionsKnow what to do in an emergency
17IRR99 – duties of employer Appointment of Radiation Protection AdvisorAn RPA must be consulted on the implementation of these regulations.Prior examination of plans.Critical Examinations of equipmentPeriodic testing of control measuresImplementation of requirements for controlled and supervised areasCalibration of instrumentsDose limitation proceduresPPE, Training, Outside Workers etc.and more
18IRR99 – duties of employer Selection, maintenance and quality assurance of medical equipment.Area monitoringTrainingProvide suitable Personal Protective EquipmentCo-operation between employersHolding sealed sourcesAccounting and movement of radioactive substancesReporting incidents
19IRR99 - Duties of Employees No one must knowingly expose himself or any other person to ionising radiation to an extent that is greater than is reasonably necessary for the purposes of his work.Personal Protective Equipment must be used in the correct manner if provided.
20Radioactive Substances Act 1993 (RSA 1993) Must register all sources with Environment Agency (in Scotland SEPA)Must obtain authorisation to store and dispose of waste
21Registration of Sources RSA 1993Registration of SourcesPremises where source kept (Section 7 (2) (a))Undertaking on premises - hospital (Section 7 (2) (a))Use of sources Section 7 (2) (c)Description Section 7 (2) (d)what and how muchSeparate application forSealed SourcesUnsealed SourcesMobile Sources Sections 3 & 9
22Authorisation for disposal and accumulation of radioactive waste RSA 1993Authorisation for disposal and accumulation of radioactive wastePremises where the waste is to be disposed ofRoutes – Waste contractor, sewerForm- Solid, liquid or Gaseousand activity
23RSA 1993Record KeepingThe employer is responsible for keeping sufficient records, of sources holdings, waste storage and waste disposal.
