ABSTRACT
The National Institute of Standards and Technology (NIST) measured the internal pair production branching ratio of 90Y using two sources and four high purity germanium (HPGe) detectors to detect the resulting annihilation radiation. The internal pair production branching ratio determined from these measurements, (32.0⯱â¯1.5)â¯×â¯10-6 (kâ¯=â¯1), agrees within 1 standard uncertainty with the recommended value of (32.6⯱â¯0.7)â¯×â¯10-6 (kâ¯=â¯1) from the DDEP database.
