  • Method and apparatus for indicating the radioactive decay products of radium in an environment
    Patent number: 3988587
    Abstract: An improved method and apparatus for providing an indication of the radiation activity of the radioactive decay products of radium in an environment wherein the alpha particle activity and the beta particle activity at a test site are detected and the detected alpha particle and the beta particle activities provide the indication of the radiation activity of radon and the decay products of radon at the test site. The background radiation activity at the test site is detected, and the detected alpha particle and the beta particle activities less the detected background radiation activity provide the indication of the radiation activity of radon and the decay products of radon.
