Radiation dose measuring element

Abstract

Abstract PURPOSE:To automatically read the classification management use number with high accuracy by attaching a tape in which a number code for a classification management is printed, to a circular outside peripheral surface of a radiation dose measuring element. CONSTITUTION:On a circular outside peripheral surface 1a of an annular radiation dose measuring element 1, a shallow groove 2 of width corresponding to roughly the thickness width is formed extending over the whole periphery, and to this groove 2, a tape 3 in which bar-codes X corresponding to a number for a classification management of the radiation dose measuring element 1 are arranged and printed in its lengthwise direction is stuck. In this state, a rotational operation of the radiation measuring element 1 at the time of reading the bar-code, and a read operation by a projector 4A and a light receive device 4B are executed plural times. In such a way, the number for a classification management can be read automatically with high accuracy.
