کنترل کیفی و کالیبراسیون دستگاه های دزکالیبراتور RAMS-88 در مراکز پزشکی هسته ای ایران

  The aim of this paper is the examining ways for quality control and calibration of Rams-88 calibrator. The device measures the amount of &gamma and &beta rays in radio medicines by means of the amount of radioactivity of radio nuclide. In this paper experiments has been done for explaining correct operation of these devices using standard method including precision, accuracy and linearity of response and position sensitivity. Minimum errors resulted for precision, accuracy and linearity of response using standard method of IAEA-Tecdoc-602. The position sensitivity experiment was carried out by changing of source height in a holder of radioactive source in dose calibrator. An error of near %5 was resulted for the height of 0 - 4 cm, while the maximum error of about %30 was obtained for the height of 5 -10 cm.
