Scintillation Counter is an instrument that is used for measuring ionizing radiation. “It comprises of the scintillator that generates photons in response to incident radiation”, a PMT tube is used to convert an electronics and electric signal to process the signal.
A scintillation counter is used to detect gamma rays and a presence of a particle. It can also measure the radiation in the scintillating medium, the energy loss or the energy gain. The medium can either be gaseous, liquid or a solid. The scintillator counter is generally comprised of the transparent crystalline material such as glasses, liquids or plastics. One sector of the scintillators is placed (optical contact )with the pin code.
A charged particle loses energy when passing through the scintillator thus leaving the trail of excited molecules and atoms. A rapid interatomic transfer of electronic excitation energy follows, which leads to the burst of scintillator material ( luminescence characteristic. The scintillation response, when a particle stops leading to the light output. The energy loss of a particle is measured when a particle passes completely through a scintillator.
Applications of Scintillation Counter
- Scintillation Counters are widely used in radioactive contamination, radiation survey meters, radiometric assay, nuclear plant safety and medical imaging, that are used to measure radiation.
- There are several counters of mounted on helicopters and some pickup trucks for rapid response in case of a security situation due to radioactive waste or dirty bombs.
- Scintillation counters designed for weighbridge applications, freight terminals, scrap metal yards, border security, contamination monitoring of nuclear waste and ports.
- It is widely used in Screening technologies, In vivo and ELISA alternative technologies, cancer research, epigenetics and Cellular research.
- It also has its applications in Protein interaction and detection, academic research and Pharmaceutical.
- Liquid Scintillation Counter is a type of scintillation counter that is used for measuring the beta emission from the nuclides.
