Radiation safety has been based for many years on verification of compliance with regulatory requirements, codes of practice and international standards, which can be considered prescriptive methods. Accident analyses have been published, lessons have been learned and safety assessments have incorporated the need to check whether a facility is ready to avoid accidents similar to the reported on...

Radiation is used to sterilize Medflies, Ceratitis capitata (Wied.), for SIT programmes. Massreared flies in the Madeira-Med sterile insect technique (SIT) programme are sterilized at the pupal stage about 24 hours before adult eclosion with 100 Gy using a Gamma Cell 220 loaded with Cobalt 60. The pupae are in anoxia/hypoxia when treated. It is known that the higher the radiation dose given to ...
