IONISATION CHAMBER

Patent ·
OSTI ID:4005737
An ionization cbamber is described which is sensitive oriy to certain radiation in mixed radiations and whose current can be adjusted. The chamber comprises two concentric zones separated by a measuring electrode, each zone containing a high-tension electrode. The outer zone also contains a grid and is filled with a gas and provided with suitaible walls so that iorization is produced by only one kind of radiation. Tbe inner zone is likewise constructed so that ionization is produced by both the aforesaid radiation and a second kind of radiation. In separating mixed radiations, the current produced by one kind of radiation is canceled by adjusting the grid potential so that only the other kinds of radiation are detected. (D.L.C.)
