In interventional radiology, it is necessary to know the scattered radiation at the physician’s position. Conventionally, survey meters have been used that can measure of 1cm dose equivalent[Hp(10)]. This time, We had the opportunity to use a survey meter(OD-01)that can measure of 70μm[Hp(0.07)], which can evaluate the equivalent dose(ED)of the crystalline lens. In this study, we report the basic performance evaluation of OD-01.

As a result, it was found that the OD-01 had good basic performance in terms of tube voltage dependence and angle. We consider OD-01 is useful for evaluation of ED.
