Ionising Radiations RegulationsLasermet's Interlock® control system and how it fits with the Regulations

The following is an extract from the following document “Work with ionising radiation”, Ionising Radiations Regulations 1999: Approved Code of Practice (ACOP) and guidance.

The underlined text is relevant for safety applications and the bold text shows where Lasermet’s safety related systems and equipment provides a solution to fit the requirement and provide X-ray protection.

This Approved Code of Practice and guidance gives detailed advice on the Ionising Radiations Regulations 1999. It is aimed at employers with duties under the Regulations but should also be useful to others such as radiation protection advisers, health and safety officers, radiation protection supervisors and safety representatives.

The main aim of the Regulations and the supporting Approved Code of Practice is to establish a framework for ensuring that exposure to ionising radiation arising from work activities, is kept as low as reasonably practicable and does not exceed dose limits specified for individuals. This applies to exposure, whether from man-made or natural radiation and from external radiation (eg X-ray set) or internal radiation (eg inhalation of a radioactive substance).



The Ionising Radiations Regulations 1999 (IRR99),1 made under the Health and Safety at Work etc Act 1974 (HSW Act),2 implement the majority of the Basic Safety Standards Directive 96/29/Euratom3 (BSS Directive) in Great Britain (Northern Ireland publishes separate regulations).

The guidance which accompanies the Regulations and ACOP in this publication gives detailed advice about the scope and duties of the requirements imposed by IRR99.

The Basic Safety Standards Directive

The 1996 Basic Safety Standards Directive (BSS Directive) reflects the 1990 recommendations of the International Commission on Radiological Protection (ICRP60). The Directive lays down basic safety standards for the protection of the health of workers and the general public against the dangers arising from ionising radiation. Implementation of the BSS Directive in Great Britain is achieved by a mixture of revised regulation (eg IRR99), existing legal provisions, such as the Nuclear Installations Act 19655 (NIA65) and the Radioactive Substances Act 19936 (RSA93), and new provisions, for example proposed regulations on emergency preparedness.

Regulation 8 Restriction of exposure

(1) 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.

Responsibility for restricting exposure

The radiation employer, as defined by regulation 2(1), has the overall responsibility for restricting exposure to ionising radiation

Under Regulation paragraph 8 (2) states:-

Without prejudice to the generality of paragraph (1) a radiation employer shall –

  1. (a) So far as is reasonably practical achieve the restriction of exposure to ionising radiation required under that paragraph by means of engineering controls and design features and in addition by the provision of and use of safety features and warning devices.

Lasermet designs, manufactures and installs certified engineering controls which include high specification safety features, (the ICS-6 Interlock® Controller) and warning devices such as the audible warning system (the Audio Alert) and low voltage, dual colour, dual message, LED signs which can include a fault indicator and can be monitored remotely.
