HPS N43.6 PDF

This standard establishes a system of classification of sealed radioactive sources based on performance specifications related to radiation safety. It does not consider the radiation output of the sealed source.

It provides a manufacturer of sealed radioactive sources with a set of tests to evaluate the safety of his products under specified conditions, and also to assist a user of such sources to select types which suit the application he has in mind especially where protection against radioactivity is concerned. This standard may also be of guidance to regulatory authorities.

The tests fall into several groups including, for example, exposure to abnormally high and low temperature and a variety of mechanical tests. Each test can be applied in several degrees of severity.

Although the standard classifies sealed sources by a variety of tests, it does not imply that the sealed source will maintain its integrity if used continuously at the rated classification. For example, a sealed source tested for one hour at 600 ºC may, or may not, maintain its integrity if used continuously at 600 ºC.
