Harshaw TLD Dosimeter Holder Insert


The Harshaw TLD Holder Insert is a unique way to take advantage of the various Harshaw TLD™ dosimeter holders, such as the 8814, with loose TLD material. If your Dosimetry Services are using bare TLD square chips or round pellets in your own holder design, this is a perfect solution for you. The insert fits into the TLD holder instead of a Harshaw TLD card and may be glued in place, if desired.

Flexibility of the design allows the use of 1 to 4 elements for penetrating dose Hp(10), skin dose Hp(0.07), eye dose Hp(3) or neutron dose with a combination of TLD-600 and TLD-700 elements. 

Various Harshaw TLD holders may be used with the Insert, such as the 8814, also known as the 8890, which provides filtration for Hp(10) with a Teflon filter, Hp(0.07) with the Mylar window, Hp(3) with 300 mg/cm2 ABS plastic and a copper (Cu) energy discrimination filter. Utilizing the 8825 TLD holder would provide an enhanced filtration with the addition of a tin (Sn) filter.

Either LiF:Mg,TI, composed or TLD-100, TLD-700 or TLD-600 may be used as well as high sensitivity LiF:Mg,Cu,P in the TLD-100H, TLD-700H or TLD-600H composition.

For environmental Dosimetry the 8855 TLD holder family may be used with the TLD Holder Insert to achieve measurements for H*(10) and H’(0.07, Ω). Similarly, the 8806 TLD holder may be used for neutron dosimetry when pairs of TLD-600 & TLD-700 are utilized.
