Ionization chamber is a very typical nuclear radiation detector. When the gamma ray is irradiated to the ionization chamber of the detection unit, the ionization chamber collects a current signal, which is directly proportional to the activity.
The 4 PI gamma well type ionization chamber is a pressurized ionization chamber, designed for the 4 PI solid angle well geometry structure, making the detection efficiency higher. The sensitive volume of the cavity is 5.2 liters, which is filled with 1MPa mixed inert gas. It can also be customized according to the user's measuring range and activity.
Energy range: beta nuclide above 25Kev and gamma above 1Mev.
Current range: (10-5-10-13) A
The typical background current is 0.03pA
