Dose calibrator sources

#{name}

 

The dose calibrators are sealed sources, made in a plastic bottle allowing easy and safe handling. The radionuclide is distributed homogeneously within a thermosetting resin. The radionuclides supplied by the LEA emit gamma rays close to those of the radionuclides most used in nuclear medicine (18F, 99mTc, 123I, 131I, 111In, 201Tl).
