Evaluation of commercial dyed plastic film for gamma-radiation dosimetry

الملخص EN

The radiation response ،؛hara،؛terist؛cs of a commercially available plastic film tinted with red dye has been investigated, as well as its pre- and post-irradiation stability.

By using this film, a wide range of absorbed doses may be measured (ل© to 600kGy).

The new film dosimeter is flexible, rugged, and stable on extended storage before and after irradiation.

A computer program has been used for regression analysis of thickness and dye variations in this plastic film.

The results indicate a fairly uniform distribution of dye within, and thickness of, the plastic material.

This thin dyed plastic dosimeter is widely available in large quantities and inexpensive, which make it suitable for high-dose photon applications as a routine monitor in radiation processing.
