Gamma ray detector and method of detecting gamma ray

Abstract

In various embodiments, a gamma ray detector is provided. The gamma ray detector may include a converter element, configured to release an electron when a gamma ray moves at least partially through the converter element. The gamma ray detector may further include a semiconductor detector, arranged to receive the electron and configured to produce a signal when the electron moves at least partially through the semiconductor detector; and an amplifier circuit, coupled to the semiconductor detector and configured to amplify the signal produced by the semiconductor detector. In the gamma ray detector, the converter element may be arranged to at least partially shield the amplifier circuit from electromagnetic radiation.

Description

technical field [0001] Various embodiments relate generally to gamma ray detectors. In particular, various embodiments relate to semiconductor gamma ray detectors. Background technique [0002] A person may be exposed to radioactive radiation (also called nuclear radiation), such as man-made radiation emitted by nuclear power reactors or by systems (such as accelerators) or materials used in medical applications. In addition, natural radioactive radiation can occur in some materials. The material can undergo a concentration process that results in an increase in its radiant energy level. Nonetheless, such materials can be used in everyday products, for example in industry or construction, where they can be used without protective measures such as walls configured to shield against radiation. [0003] Furthermore, however, someone who has an unknown exposure to a described radioactive radiation source may also feel safer if he or she has sensors for the radioactive radiati...

Problems solved by technology

However, bulky germanium (or more generally, semiconductors) may still be required for acceptable detection probabilities, again making miniaturization difficult

Also, germanium is very expensive
