1   Scope

  [ISO 7503](/search?q=ISO%C2%A07503) (all parts) and [ISO 8769](/search?q=ISO%C2%A08769) are addressed to the people responsible for measuring the radioactivity present on
  solid surfaces. 
This part of [ISO 7503](/search?q=ISO%C2%A07503) applies to the evaluation of contamination on surfaces in terms of activity per unit
  area by an indirect method of measurement. 
This part of [ISO 7503](/search?q=ISO%C2%A07503) 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](/search?q=ISO%C2%A07503) can be used for laboratory and equipment/installation control and for remediation
  and monitoring activities to comply with release criteria. 
This part of [ISO 7503](/search?q=ISO%C2%A07503) also refers to institutions/authorities controlling nuclear material transports or
  material/equipment clearance according to national legislation guideline values or
  international convention limits. 
This part of [ISO 7503](/search?q=ISO%C2%A07503) 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](/search?q=ISO%C2%A07503%E2%80%911). The calibration of instruments for the evaluation of radioactive surface contaminations
     is dealt with in [ISO 7503‑3](/search?q=ISO%C2%A07503%E2%80%913).
