Ionising Radiation Dosimetry

Radiation Dosimeters are issued to radiation workers using medium to higher energy beta and gamma emitters. They are not issued to those working with tritium, carbon-14 or sulphur-35 as these are too low an energy to be detectable and the particles only have a short range. Wearers are responsible for looking after their dosimeter and changing it via their RPS at the end of the wear period - usually the end of March, June, September and December.

The dosimeter provider is Landauer and the dosimetry service is co-ordinated by the Safety Office Administrator (bb-safety-office@exmail.nottingham.ac.uk). When returned, the badges must be checked for contamination before being returned to the Safety Office. The RPS or other authorised person consigning them needs to complete a declaration that they have been checked before being returned. This is to protect those handling the dosimeters subsequently.
