Full Description

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 a method of direct measurement and an indirect method for removable surface contamination. Evaluation of surface contaminations from beta-emitters (maximum beta energy greater than 0,15 MeV) and alpha-emitters is dealt with in ISO 7503-1, other radionuclides of practical importance will be dealt with in a future standard.
