red-01This is a widely used material covering the range 5 – 50kGy. It is recommended that the radiation-induced darkening is measured at 640 nanometres (nm) wavelength where post-irradiation changes are minimised.
amber-3This is a more sensitive Perspex dosimeter material covering 1-30kGy dose range.  The recommended read-out wavelengths are 603 and 651nm.
2005-233Uniquely labelled and barcoded blister packed alanine pellets which exploit the dose-dependence of the paramagnetic resonance of alanine to provide enhanced precision and accuracy over a wider dose range.
