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
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
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 electrode, a means for adding and removing charge from the central electrode, a means for reducing or eliminating charge leakage from the central electrode, and a means for sampling the environment external to the device.
