HC Deb 04 March 1986 vol 93 c98W
Mr. Frank Cook

asked the Paymaster General what changes were introduced into the methods of (a) assessing and (b) recording exposure of workers to radiation under the regulations which came into force on 1 January; whether, under the new regulations, there are any circumstances in which the dose record of a worker exposed to radiation either internally or externally will show a lower level of recorded exposure than previously would have been recorded for the same exposure; and if he will make a statement on the implications of the revised regulations for the interpretation of the cumulative dose records of workers exposed to radiation both before and after 1 January.

Mr. Trippier

The following changes in assessing and recording exposures of workers were introduced by the Ionising Radiations Regulations 1985(a) any committed dose received from internal radiation must now be assessed, as well as any actual dose from external radiation, and (b) the dose record must show the sum total of committed and actual dose received. There are no circumstances in which a lower level of dose will be recorded under the new regulations than would have been recorded under the previous regulations. There is no requirement in the new regulations for a record of cumulative dose.
