Dose Calibrator Linearity Testing Using an Improved Attenuator System
Nuclear Regulatory Commission (NRC) guidelines state that dose calibrators must be tested for linearity upon installation and quarterly thereafter over a range of activities from 10 ~J,Ci (370 kBq) to the highest dose administered to the patient (300 mCi [11.1 GBq] ofiodine-131 for therapy at our institution). The simplest method of linearity testing utilizes commercial attenuator kits. These k...
متن کاملDose Calibrator Performance and Quality Control
Two different dose calibrators were studied and their performance measured using the following tests: (A) linearity of response over all activity ranges, (B) accuracy when measuring some commonly used radionuclides, (C) the effect of container configuration on the accuracy of measurement, and (D) daily and long-term stability of the instrument. For each instrument tested, a good linear response...

As part of the program to ensure quality in nuclear medicine unit, in addition to diagnostic procedures, are evaluated activity meters, which is intended to measure the aliquot of radiation of radionuclides and / or radiopharmaceuticals that are administered to patients undergoing diagnostic investigation and / or therapeutic treatment. The good operating condition of dose calibrators is essent...
متن کاملDose calibrator linearity test: 99mTc versus 18F radioisotopes*
OBJECTIVE The present study was aimed at evaluating the viability of replacing (18)F with (99m)Tc in dose calibrator linearity testing. MATERIALS AND METHODS The test was performed with sources of (99m)Tc (62 GBq) and (18)F (12 GBq) whose activities were measured up to values lower than 1 MBq. Ratios and deviations between experimental and theoretical (99m)Tc and (18)F sources activities were...
