Measurement of high doses near metal and ceramic interfaces

OSTI ID:6435832
Radiochromic dosimeters consisting of leuco dyes dissolved and cast in very thin (5 to 100 micrometer) plastic films have been shown to be accurate and reproducible dosimeters for measuring absorbed doses in the range 1,000 to 1,000,000 Gy. There are also thin, optical-quality ceramic crystals (e.g. LiF, NaCl and CaF/sub 2/) having thicknesses about 0.1 to 2 mm that can provide precise absorbed dose readings in the range 100 to 1 billion Gy by spectrophotometric readings of a series of radiation-induced color-center absorption bands. Besides their relatively broad-response ranges, these dosimeters have the advantages of being useful in both photon and electron radiation fields, without great losses in accuracy due to rate or temperature dependence. The plastic films are particularly useful for mapping high-resolution dose distributions, such as depth-dose or isodose contours in thin layers, tubing, and wire insulation. It has been shown that, by suitable selection of these plastic and crystalline systems, a fairly wide assortment of materials can be simulated in terms of radiation-absorption properties over wide photon and electron spectral ranges (0.01 to 10 MeV).
