Harwell Amber 3042

Harwell Amber 3042 Dosimeters

Amber 3042 are made from radiation-sensitive poly-methylmethacrylate （pmma） in the form of optically transparent pieces individually sealed in laminate sachets. They darken when irradiated, and the radiation-induced darkening, accuray measurable by means of a spectrophotometer, is a function of the radiation dose absorbed.

Dose Range

Amber 3042 has a functional dose range of 1 kGy to 30 kGy which makes it idea for low dose irradiation processes.

Material

The Amber 3042 is made from single batches of cast sheets of poly-methylmethacrylate （pmma）

Dimensions

Harwell Dosimeters then cut the sheets down into plaques of 30mm x 11mm with a thickness of 3mm （+/- 0.55mm）

Packaging

After * inspection the dosimeters are packaged into sealed sachets made of polyester/aluminium foil/polyester/polyethylene laminate. With each sachet being labeled with a unique bar coded label.

Packed 1,000 per carton.

（Packing to defined AQL's checked to BS6001 （ISO 2859-1）, single normal inspection, level II.）

Measurment reproducibility

Coefficient of variation of specific absorbance measurements on sets of dosimeters for the batch, simltaneously irradiated together, in a gamma radiation field uniform within +/- 1%, is 2.5% over the entire calibrated range, 1 to 30 kGy.

Calibration quality

Over the calibrated range, all mean specific absorbance data points thus obtained are within 3% of a fourth-order polynomial least-squares fit to the data.
