Harwell RadspinHarwell RadSpinWhen pellets containing the amino acid alanine are irradiated, stable free radicals are produced in concentration which depends on exposure. The measured response to microwaves of the pellet placed in a manetic field of a paramagnetic resonance spectrometer, is quantitively related to the radiation dose which the pellet absorbed. Dose RangeRadspin has a functional dose range of 0.1 kGy to 70 kGy (0.01 kGy to 100kGy may also be achieved) which makes it idea for almost any range of irradiation processes.
