RPS Update
The Justification of Practices Involving Ionising
Radiations Regulations 2004 [SI No. 1769]
Introduction
Exposure to ionising radiation can lead to harmful
effects in humans. Justification is therefore one of the key principles
of radiological protection established by the ICRP on which the legislative
framework in the UK is based. Justification involves weighing the overall
benefits of a practice, which might result in exposure of people to
radiation, against the harm likely to result from that exposure.
Purpose and intent
These regulations, which implement European directive
obligations (96/29 Euratom), provide a framework in which justification
decisions will be made. Rather than individual uses, it is particular
classes or types of practice giving rise to radiation exposure which
must be justified. New classes or types of practice will need to be
justified in advance of them being adopted. Existing classes or types
of practice may be reviewed to prove their justification whenever new
evidence about their efficacy or consequences is acquired.
Specific measures
Previously, justification decisions were taken
on a site-by-site basis by the regulators when considering individual
applications under the RSA93. These regulations introduce procedures
for deciding the justification on a generic basis and for the review
of existing practices when circumstances change. In addition, the regulations
also (i) prohibit the addition of radioactive materials to certain goods
(personal ornaments, toys and cosmetics) and the import and export of
such goods, and (ii) permit individually justified medical exposures
where the class in general is not justified.
