Handling - Vacuum tweezers should always be used. (Avoid mechanical tweezers or fingers). Small scratches, loss of mass or foreign deposits affect light emission.
Cleaning - Rinse the dosimeters in analytical grade anhydrous methyl alcohol between normal uses. (Do not soak). Dry by leaving to evaporate for at least one hour. Anneal once before actual use, accurately following the established procedure. The anneal will also assist in removing any residual methyl alcohol.
Annealing - For annealing temperatures up to 400°C, the containers should be made from high temperature stainless steel or oxidized aluminum, preferably thin to assist rapid cooling following annealing. (Do not use non-oxidized aluminum). The use of a dedicated annealing oven reduces the risk of contamination by foreign material. Place the annealing containers on open oven racks with air space all round to avoid inconsistent heat gradients. (Do not stack containers or allow them to touch the oven walls).
