•Scintillation detectors: •Impinging particles will excite atoms or molecules of the scintillating medium. •The decay of these excited states will produce photons in the visible part of the spectrum. •These photons will be guided to a photodetector and converted in an electric signal.

A 2x2 inch sodium iodide (NaI) detector will allow the user to identify the presence of Cs137 at < 1 urem/hr/sec. The 3x3 inch NaI detector can identify Cs137 at 500 nrem/hr/sec. This is why BNC’s SAM III generation and SAM 940 are designed to easily hold large detectors and operate them with one hand.

LaBr3 (Ce) crystals are a newer type of scintillation detector material ideal for applications requiring long-term unattended scintillation detectors. • Applications.

Scintillation detector 50. Scintillation detector • Scintillation detector works on principle of detection of ionizing radiation by measuring the scintillation light produced by certain materials like NaI, CsI, Cadmium tungstate ,amorphous silicon etc., • When the crystals absorb the energy the e- jump from ground state to conduction band.

The scintillation detector constitutes one of the most useful tools available for the detection of a wide range of radiation. The principle of scintillation detector is the in-teraction of the incident radiation with a scintillating ma-terial that releases the energy deposited in the form of light photons.

Scintillation Counter How it Works. Let us try to understand the principle of scintillation counter through the following points. When ionizing incident radiation enters the scintillator, it interacts with the material of the scintillator due to which the electrons enter an excited state. A scintillation counter is a radiation detector instrument that is used to measure ionizing radiation. A scintillation counter is made up of a sensitive photodetector (usually a photomultiplier tube), a charge-coupled device camera (CCD) which converts light to electric signal and a scintillator which generates photons in response to incident radiation. Scintillation detectors usually employ a Voltage Divider (VD) network to operate the PMT. This sometimes called “bleeder network” defines a potential (voltage) difference between the cathode, dynodes and anode of the PMT. The exact design of this network is of influence for proper working of the scintillation detector. 2006-02-10 · NaI:Tl-based scintillation detectors were repeatedly used in recent satellite missions [174, 175].

The intensity of the flashes is proportional to the energy of the radiation. This feature is very important.
