The measured response to microwaves of the pellet placed in a magnetic field of a paramagnetic resonance spectrometer, is quantitatively related to the radiation dose which the pellet absorbed.
Radspin has a functional dose range of 0.1 kGy to 70 kGy (0.01 kGy to 100kGy may also be achieved) which makes it ideal for almost any range of irradiation processes.
