Abstract:
The device manufactured is equipped with the NaI(Tl) scintillation crystal situated in a thick lead shielding. The cavity in the lead shielding allows inserting a hand which is in contact with the detector during the measurements. The apparatus exhibits low values of the minimum detectable superficial activity of radionuclides emitting low energy gamma-rays (e.g. 125I, 99mTc). The apparatus complies with the requirements for a sensitive and prompt monitoring the contamination of hands in departments of nuclear medicine with the numerous staff.
