Product Detail:
Applies to surfaces of equipment and facilities, containers of radioactive materials and sealed sources, does not apply to the skin and contamination of clothing. Gives direct and indirect methods of measurement (the latter by means of smear tests). Is restricted to beta- and alpha-emitters, the production rate of which, with regard to beta-particles plus monoenergetic electrons and alpha-particles resp., is near to 100 particles per 100 decays. Evaluation of tritium surface contamination is dealt with in ISO 7503-2, other radionuclides of practical importance will be dealt with in a future standard.
