Title: Process and apparatus for detecting presence of plant substances

Abstract

An apparatus and process for detecting the presence of plant substances in a particular environment which comprises the steps of: measuring the background K40 gamma ray radiation level in a particular environment with a 1.46 MeV gamma ray counter system; measuring the amount of K40 gamma ray radiation emanating from a package containing a plant substance being passed through an environment with a counter; and generating an alarm signal when the total K40 gamma ray radiation reaches a predetermined level over and above the background level.
