title: Research and development of a radioisotope dose calibrator with background alarm used in nuclear medical laboratories.
abstract: In this study, research and development of a prototype background alarm levelled radioisotope dose calibrator for nuclear medical laboratories was emphasized. The aim was to develop a standard performance, economical dose calibrator (self-made) from the ion-chamber to the microcomputer. Dose calibrators are used in nuclear medical laboratories for treatment and diagnosis purposes. The device is developed using an ion chamber filled with 2 atm pressure argon gas, 3N201 dual gate mosfet for the extremely high impedance preamplifier, an Intel 8052AH microcontroller for the microcomputer, ADC0804 for the A/D conversion, a Phillips 2 x 16 character display, and other components. Correction factors are used for each radioisotope after the activity measurements, that can be updated and kept in the Ni-Cd rechargeable battery-powered RAM memory. To provide safety in nuclear medical laboratories, background activity values are measured.
