Harwell Dosimeters Limited
Dosimeters for the Radiation Processing Industry
This 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.
This is a more sensitive Perspex dosimeter material covering 1-30kGy dose range. The recommended read-out wavelengths are 603 and 651nm.
Gammachrome YR™ are made from radiation-sensitive poly-methylmethacrylate (pmma) in the form of optically transparent pieces individually sealed in laminate sachets. They measure low doses from 100Gy to 3kGy They darken when irradiated, and the radiation-induced darkening, accurately measurable by means of a spectrophotometer, is a function of the radiation dose absorbed.
Uniquely 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.
The newest edition to our alanine product portfolio. Alanine pellets presented in a barcoded strip package. The pellets remain in their packaging for assessment and demonstrate continual traceability and identification.
