Abstract
Disclosed is a radiation detector including a thallium bromide crystal, and a first electrode and a second electrode facing each other with the thallium bromide crystal interposed therebetween. The thallium bromide crystal contains 0.0194% to 6.5% by mass of chlorine atoms based on a mass of the thallium bromide crystal.
Claims5
A radiation detector comprising:
- a thallium bromide crystal;
- and
- a first electrode and a second electrode facing each other with the thallium bromide crystal interposed therebetween,
- wherein the thallium bromide crystal comprises 0.0194% to 6.5% by mass of chlorine atoms based on a mass of the thallium bromide crystal.

A method for producing a radiation detector, comprising, in order:
- performing a refining treatment on a thallium bromide raw material comprising impurities including chlorine atoms 20 times or less by a zoned melting and refining method;
- growing a thallium bromide crystal from the thallium bromide raw material to obtain a thallium bromide crystal containing 0.0194% to 6.5% by mass of chlorine atoms based on a mass of the thallium bromide crystal;
- and
- forming a first electrode and a second electrode facing each other with the thallium bromide crystal interposed therebetween.
