[2D07] Radiation safety management for Crookes tube that radiate high leakage dose

*Masafumi Akiyoshi1 (1. Osaka Prefecture Univ., Rad. Res. Center)

Keywords:Crookes tube, Low energy X-rays, the general public, dose constraints, radiological education

Character of Crookes tube used in education field is differ with each equipment. One Crookes radiate quite strong X-rays up to Hp(0.07)=200mSv/h at 15cm from the surface. With this Crookes tube, applied voltage - current correlation, leakage dose and energy spectrum of X-rays were investigated to discuss the act for radiation safety management.
