Detectors and measuring equipment

Suitable detectors and radiation measuring equipment are required to be able to detect and measure radioactivity. Depending on the type of activity to be measured, the following are used as detectors  

Detectors for particular purposes, e.g. gas-filled counters, or counters for very low activities 

Counter combinations with anticoincidence circuit (measuring counter surrounded by a ring of protective counters which lower the zero effect). 

Large-area counters with anticoincidence circuit and appropriate lead screening, combined with a suitable measuring and evaluation unit, are frequently selected as detectors in water analysis. 

An ionization chamber functions in the field of saturation, with the saturation voltage applied siphoning off all charge carriers created by ionization of charged particles along their path. In this phase, a linear relationship exists between pulse height and saturation voltage.
