RT Journal Article SR Electronic T1 Radiation Safety Considerations for PET Centers JF Journal of Nuclear Medicine Technology JO J. Nucl. Med. Technol. FD Society of Nuclear Medicine SP 98 OP 102 VO 25 IS 2 A1 Brown, Terry F. A1 Yasillo, Nicholas J. YR 1997 UL http://tech.snmjournals.org/content/25/2/98.abstract AB This article explains why technologists handling positron-emitting radionuclides may have higher measured radiation exposures than technologists working with single-photon emitting radionuclides. We will summarize measurements we have made, as well as those reported by other authors. In addition, we will describe the procedures implemented to minimize exposure.
