ASTM D7362-14 + Redline

1.1 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.
