ASTM D7362 - 2014 Standard Guide for Rapid Screening of Vegetation for Radioactive Strontium Aerial Deposition

American Society for Testing and Materials - 2014.- 4 p.
This guide provides a rapid procedure by which vegetation samples may be screened for surface contamination of radioactive strontium (89Sr and 90Sr, collectively referred to as radiostrontium) following an airborne radioactive dispersal event. It provides a conservative estimate of radiostrontium deposition that can be used by decision makers for immediate actions prior to obtaining definitive results from a fixed laboratory asset.
Insoluble forms of radiostrontium, such as the strontium (90Sr) titanate (SrTiO3) used in radioisotope thermal-electric generators (RTGs), will not be measured by this method.
