RT Journal Article SR Electronic T1 Comparison of Attenuators for Linearity Testing of The Dose Calibrator JF Journal of Nuclear Medicine Technology JO J. Nucl. Med. Technol. FD Society of Nuclear Medicine SP 111 OP 115 VO 16 IS 3 A1 George J. Dydek A1 Peter W. Blue A1 Harry N. Tyler, Jr. YR 1988 UL http://tech.snmjournals.org/content/16/3/111.abstract AB The performance of two commercially available attenuator devices used for dose calibrator linearity testing are evaluated. Although both devices function adequately, the use of the manufacturers’ recommended instructions may result in test results that misrepresent the dose calibrator’s performance. Recommendations for proper use of the attenuator devices are presented as well as a step by step protocol.
