Study on a New Label Dosimeter for Radiation Processing

In order to monitor the absorbed dose of goods in ⁶⁰Co γ-rays and electron beams, a new label dosimeter had been developed for dose measurements. The label dosimeter had a multilayer structure, and the core of which was a layer of radiochromic film. The radiochromic film contained acid-sensitive dye and halogen compound in polyvinyl alcohol (PVA),and the dosimetry of the film dosimeter was studied, the result showed that the dosimeter was satisfied for daily radiation business.
