Commonly used scintillator for measuring radiation is
(a)NaI(Al)
(b)NaI(Tl)
(c)CsI(Tl)
(d)CsI(Al)
Answer
Answer (as printed): B
Explanation
Cesium iodide (CsI) in crystalline form is used as the scintillator for the detection of protons and alpha particles. Sodium iodide (NaI) containing a small amount of thallium is used as a scintillator for the detection of gamma waves and zinc sulfide (ZnS) is widely used as a detector of alpha particles. Since in the question, it is asked about radiations (that means gamma rays) thus answer should be NaI
