Electroscope and condenser ion chamber for the measurement of radioactive materials such as radon, thoron, tritium, radon progeny, beta emitting gases and alpha, beta, neutron, x-ray and gamma radiation

Abstract From the Canadian patent

Disclosed is an electroscope and condenser ion chamber suitable for detecting and for measuring radiation radioactive gases, and, radioactive aerosols in the ambient environment said radiation, being alpha particles, beta particles neutrons, x-rays and gamma, rays, said radioactive gases being radon thoron, tritium, and, said radioactive aerosols being radon progeny said radiation, radioactive gases and radioactive aerosols having levels of radioactivity ranging from low environmental to high levels and, said measurements being made at diverse humidities and, measurement times. The device is comprised of an ion chamber a, means for determining the charge level on an insulated central …
