Thermoluminescence Dosimetry
Accessories
Model TL-758, Vacuum Tweezer System consists of a double-insulated vacuum pump that delivers 355mmHg vacuum at 125 cubic inches per minute, a bypass pick-up probe, inline filter, and five interchangeable pickup tips. The vacuum pump operates on 110 Volts AC (220 Volts also available). TL dosimeter handling with a vacuum pick-up probe is fast, and will not mar, scratch or contaminate crystal surfaces.
Model TW-108, Teflon Tipped Tweezers is specially designed for handling TL dosimeters. Made of stainless steel with smooth, wide, teflon-coated tips that will not mar, scratch or contaminate crystal surfaces.
Easy Transfer Dosimeter Storage Containers provide a convenient means of transfer of TL dosimeters to an annealing planchet or irradiation phantom. Each row of spaces is numbered horizontally and vertically, identifying the dosimeter location. A cover with thumb screw fasteners provides spill-proof and
dust-proof storage of TL dosimeters.
To transfer TL dosimeters to the planchet or irradiation phantom, line up the numbers, fasten together with screws and turn over. To store dosimeters, the procedure is reversed.
Irradiation Phantoms are available in polystyrene for insertion in a 25 x 25cm polystyrene stack. Plastic Water® and Solid Water® are available for insertion in a 30 x 30cm stack. Dosimeter space and numbering patterns are mirror images of corresponding storage containers for convenient transfer of dosimeters.
Anodized Aluminum Annealing Planchets measure 10 x 12 x 0.63mm; compact enough to fit heating chambers of TL-925/955 Annealing Ovens.
Model 159-000 has 50 machined spaces measuring 3.1 x 3.1 x 8.2mm to accommodate up to 50 rod dosimeters.
Model 163-000 has 100 machined spaces, 5.4mm diameter, 4.5mm deep, to accommodate ribbon or disk dosimeters. The dosimeters lie flat and in good thermal contact, allowing rapid heat transfer. Dosimeter space and numbering patterns are mirror images of corresponding storage containers for convenient transfer of dosimeters. An acrylic cover with two thumb screws securely retains dosimeters in their location after cool down.
The vacuum tweezers are especially recommended for placing dosimeters in the planchet. To clean the spaces, use cotton swabs, dry or with methanol.
Model 163-002, Planchet Handle - Stainless steel handle inserts into a heating planchet to provide safe handling of hot planchets when being removed from the annealing oven.
Model 164-000, Brass Cooling Plates - The cool down of annealing planchets is greatly accelerated when sandwiched between this set of two brass plates. Each plate measures 15.2 x 15.2 x 2.5cm, and weighs 11 lbs. This mass provides ample thermal storage capacity and the high thermal conductivity of brass provides fast heat transfer from the planchets. One plate has a large heavy-duty handle attached.
