Abstract : A chlorinated hydrocarbon sensor is substituted as a portion of a cone penetrometer. The sensor includes a titanium casing in which a cylindrical sleeve of beryllium alpha target material is fixed. A rod-shaped americium alpha particle source is disposed within the casing and is moved by an electromagnetic relay into an interacting state in which the beryllium sleeve encases the americium alpha particle source. The interfacing beryllium and americium emit high energy neutrons used to detect the chlorinated hydrocarbons. jg p.1
