Linearity on dose calibrator
NettetThe dose calibrator is to be tested for linearity upon installation and at least quarterly thereafter (10 CFR 35.50(b)(3)). Licensees have frequently not determined linearity over the entire range of use. Technetium-99m is most frequently used for the linearity test because of its availability and short half-life, and it is relatively inexpensive. NettetDose calibrator linearity testing is indispensable for evaluating the capacity of this equipment in measuring radioisotope activities at different magnitudes, a fundamental …
