Radiation Detectors Part III : Dose Calibrators (Ionisation Chamber based detectors Part -I)

This video is a complete guide about Dose Calibrators used in Nuclear Medicine. This will explain working principle and design of dose calibrators, the Argon gas used and why, the pressure of gas, The calibration factors, Quality control and acceptance testing of Dose calibrators, Recombination - Columnar and Volumetric, Voltage response curve, Energy response curve of dose calibrators. The Photo electric effect and Compton scattering at various energies are explained in details. The other videos of this series are: 1.
