DOSE AREA PRODUCT VALUES OF FLUOROSCOPICALLY GUIDED PAIN MANAGEMENT PROCEDURES: COMPARISON OF A BELGIAN TEACHING HOSPITAL WITH NATIONAL DIAGNOSTIC REFERENCE LEVELS.

abstract：:The novel DIS-1 dosemeter developed by RADOS is based on ionisation chambers with so-called Direct Ion Storage (DIS). The dosemeter can measure Hp(10) and Hp(0.07) of photon and Hp(0.07) of beta irradiation. The characteristics of the commercially available DIS-1 dosemeter were studied at the Paul Scherrer Institute, ...
