求翻译：(d) The detector must have a sensitivity of at least 7 counts per minute per kilobecquerel of technetium-99m (a kilobecquerel is a unit of radioactivity and is equal to 1000 disintegrations per second) using a 20 percent energy window and low-energy, high-sensitivity collimator, and measured according to the National Electrical Manufacturers Association, Performance Measurements of Scintillation Cameras (NEMA Standards Publication NU 1-1994).是什么意思？
