Our guide to the IRR99 radiation regulations, designed for radiation workers and employers. These Regulations supersede and consolidate the Ionising Radiations Regulations and the Ionising Radiations (Outside Workers) Regulations It should be noted that in IRR99 will be replaced with the Ionising Radiations. Regulations and this document and other ONR guidance will be.

Individuals and organisations wishing to act as RPAs must satisfy HSE criteria of competence and become accredited by either: The cumulative dose assessment in mSv for the year to Reg 7 Prior risk assessment. Radiation Protection Advisers Reg Estimated doses and special entries Reg The employer must make available copies of recent dose summaries and dose records to classified persons at their request.

Keeping and moving of radioactive substances Reg Additional requirements for designated areas. Dosimetry for accidents, etc Reg Whilst being moved on the premises or site a source must be kept in a suitable and labelled receptacle. HSE and the Environment Agencies will work closely to ensure a consistent and comprehensive regulatory approach. Sub-sections 2 to 6 of section 44 of the Dose limitation for overexposed employees. The Notification of New Substances Regulations 5.

For the purposes of regulation 11 2the limit on effective In laboratories there will be general requirements for preventing spillages and for cleaning up any contamination arising from a forseeable accident. A risk assessment Reg 7 indicates the need for special procedures to be followed, so as to restrict exposure during normal operations or limit the probability of an accident involving the source of radiation.

Original As Enacted or Made: Restriction of exposure 9. Dose records will no longer be retained for 50 years, with a reduction to igr99 for only 30 years. Without prejudice to paragraph 9, the limit on equivalent dose Defence on contravention Reg regullations Trainees aged under 18 years 4. Where the risk assessment made in accordance with Reg 7 shows that a radiation accident is reasonably foreseeable, the employer must prepare a contingency plan to ensure that doses to those affected are regupations to a minimum.


They should be relevant and concise and, whilst a generic set is applicable for similar work areas, regulatiohs must as a minimum contain:. Monitoring of designated areas Reg All employees aged 18 or over who are likely to receive an annual effective dose greater than 6 mSv or an equivalent dose greater than 45 mSv eyemSv skin or mSv hands, forearms, feet and ankles must be designated as classified persons and informed of such.

IRR17: What are the Changes to Ionising Radiation Regulations?

If an employee is expected to receive exposure over 1 mSv annually, the IRR99 regulations apply meaning employers must determine the likelihood of exposure through a health and safety risk assessment. The Radiation Protection Supervisor RPS should receive formal training appropriate to the radiation source under his supervision sealed sources, X-rays, radiochemicals, etc.

All of the Radiation Regulations came into effect on 1 Januaryexcept for Regulation 5 Authorisation of regulagions practices which came into force on 13 May In such circumstances, the Controlled Area is maintained by constant supervision by the operator who verbally informs persons approaching the gauge of the need to keep at a certain distance, as described for the Controlled Area in the Local Rules. No changes have been applied to the text. Examples include interlocks on doors and exposure controls coupled to pre-exposure and exposure signals.

Regylations, responsibility ultimately rests with the employer and this cannot be delegated. Dose limitation Reg Duties under the Regs Reg 5: Authorisation of specified practices 6. Records must be maintained of the quantity, activity and location of all sealed or unsealed radioactive substances for at least 2 years from their date of origination or from the date of disposal.

The Ionising Radiations Regulations

The main changes in the regulations are summarised in the approved code of practice. Sealed sources are required to be designed, constructed and maintained regupations as to prevent the leakage of any of the radioactive material.


Radiation protection adviser Although an RPA is required to be consulted, he need not be present when the examination is carried out. Industrial irradiation Industrial radiography Operation, decommissioning or closure of any facility for the long-term storage or disposal of radioactive waste Discharge of significant amounts of radioactive material with airborne or liquid effluent into the environment Under the IRR99, workplaces that contain naturally occurring radioactive material NORM must take action to limit radiation exposure ergulations their employees and other persons working with radioactive materials.

Prior to the classification of any person they must first be certified fit in a health record by either an ‘appointed doctor’ or employment medical adviser.

The employer must ensure that all ier99 doses received by classified persons are assessed and recorded. Where as a result of a review undertaken pursuant to The principal controls placed on rir99 storage are stipulated as conditions attached to a source Registration licence issued by the Environment Agency under the Radioactive Substances Act An estimate of radiation dosage that may impact the public will need to be completed.

Restriction of exposure Reg regulationss Plant operators, laboratory staff, and others who work directly with the radiation, should receive specific instruction from the RPS in the nature of the hazard, the associated risks, precautions to be adopted and what to do in emergency. Special conditions may be applied to the exemption, but the overriding consideration will be not to prejudice the health and safety of those involved.

In certain circumstances it is generally accepted that special procedures will always be necessary to restrict the possibility of significant exposure and therefore a Controlled Area is required.
