|Publication Date:||15 January 2016|
|ICS Code (Radiation protection):||13.280|
ISO 7503 and ISO 8769 are addressed to the people responsible for determining the radioactivity present on solid surfaces.
This part of ISO 7503 applies to the evaluation of contamination on surfaces in terms of activity per unit area by direct and indirect methods of measurement and deals with the complex aspects of instrument calibration.
This part of ISO 7503 is applicable to well-defined surfaces, such as those of equipment and facilities, containers of radioactive materials, sealed sources, and buildings or land.
This part of ISO 7503 can be used for laboratory and equipment/installati
This part of ISO 7503 also refers to the following:
- calibration laboratories or institutions dealing with radionuclides with complex emission characteristics or radionuclides for which no reference calibration sources are available;
- institutions confronted with the task to evaluate surface contaminations consisting of a radionuclide mixture;
This part of ISO 7503 does not apply to contamination of the skin, clothing, or loose material, such as gravel.
NOTE Direct evaluation of surface contamination from alpha-emitters, beta-emitters and photon emitters is dealt with in ISO 7503-1. The test method using wipe-test samples for the evaluation of radioactive surface contaminations is dealt with in ISO 7503-2.
