Abstract
1. The method of detecting predetermined organic halogen compounds in a gas omprising the steps of directing a sample of said gas into a reaction chamber containing immobilized therein a halogen compound in which the halogen constituent is radioactive, providing environmental conditions in said chamber to promote a chemical reaction whereby said radioactive constituent forms a mobile compound with a constituent of said organic halogen compound, and passing said sample including any of said mobile compound generated out of said reaction chamber and into the presence of a radiation detector.

The method of detecting predetermined organic halogen compounds in a gas comprising the steps of directing a sample of said gas into a reaction chamber containing immobilized therein a halogen compound in which the halogen constituent is radioactive, providing environmental conditions in said chamber to promote a chemical reaction whereby said radioactiive constituent forms a mobile compound with a constituent of said organic halogen compound and passing said sample including any of said mobile compound generated out of said reaction chamber and into the presence of a radiation detector.
Apparatus for the detection of predetermined organic chemical agents in a gaseous atmosphere comprising a reaction chamber, means for transmitting a sample of gaseous atmosphere into said reaction chamber, a quantity of immobilized halogen compound in said reaction chamber, the halogen constituent of said compound being radioactive, means for controlling the temperature of said reaction chamber, means for measuring the radioactivity of the immobilized halogen compound in said reaction chamber, means for providing a signal inversely proportional to the radioactivity of the immobilized halogen compound an outlet from said reaction chamber, means disposed away from said reaction chamber for measuring the radioactivity of the gas emitted from said reaction chamber, and means for providing an indication proportional to the radioactivity of the gas emitted from said chamber.
