This standard specifies methods for evaluating radioactive surface contamination of articles, facilities, radiation source containers, sealed radiation sources, etc. (hereinafter referred to as "articles, etc.") using surface contamination density. However, this does not apply to skin and clothing. This standard applies to radioactive surface contamination by beta-emitting nuclides and alpha-emitting nuclides with a maximum energy Eβmax of 0.15 MeV or higher. Strictly speaking, this is limited to nuclides for which the number of β particles, monochromatic electrons, or α particles produced per one decay can be considered to be approximately 1 (see Table A.3).
