Question

Which of the following is the main disadvantage of solid state semiconductor detector?

(a) Low accuracy

(b) Low sensitivity

(c) It should be maintained at low temperature

(d) High pressure has to be produced

The question was asked during an online interview.

Asked question is from Radiation Detectors in section Radiochemical Techniques of Analytical Instrumentation

Answer 1

Right choice is (c) It should be maintained at low temperature

The best I can explain: The main disadvantage of solid state semiconductor detector is that it must be maintained at low temperature. This is necessary to reduce noise and to prevent deterioration of detector characteristics.
