The 'High Activity Sealed Sources Directive' (HASS) is designed to provide greater control of high activity sealed sources. Only significant activity sources are included, for example, Cobalt-60 sources of more than 4 GBq will be included. The aim is to ensure that proper controls are in place throughout the entire life cycle of the source from production, purchase, use, storage and eventual disposal. These controls are designed to ensure that sources can not be lost, that the threat of theft is minimised, and that sources can not be purchased unless there is a disposal route and resources available to affect that disposal when required.
