RESIN-MOLDED DOSIMETER ELEMENT

摘要

PURPOSE:To eliminate gradient in the base line of an ESR spectrum and distortion of alanine spectrum, by molding a resin composition which has an alanine crystal powder and a lubricant contained in a specified synthetic resin. CONSTITUTION:A resin composition which has an alanine crystal powder and a lubricant contained in an synthetic resin wherein the amount of an isolated group (radical) generated therein by irradiation with an ionizing radiation would be less than one-tenth of the amount of radical generated in an alanine crystal by a similar irradiation or the radical generated therein would be so unstable as to damp in a short time at the room temperature down to less than one-tenth of the amount of radical in the alanine crystal is molded to form a resin-molded dosimeter element. It is appropriate to select the alanine crystal powder in a range of 10-1,000pts.wt. per 100pts.wt. of the resin. It is also appropriate to select the lubricant in a range of 0.1-20pts.wt. per 100pts.wt. of the resin.
