Production of radioactive tracers at Amersham Int
Preparation of technetium-99m (Tc-99m) isotope generators, used as sources of radioactive tracers for gamma ray scintigraphy in hospital nuclear medicine departments. Here at Amersham International, radioactive molybdenum-99 (a fission product of a nuclear reactor) is dispensed by remote control into the columns of the generators inside a " shielded facility". The glass windows contain a lead compound, which accounts for their yellow-green colour. Tc-99m is short- lived (its radioactive decay rate, or half-life, is 6 hours), so a generator fuelled by its longer-lived parent isotope, molybdenum-99, is utilised as a continuous, short-term source

EDITORS COMMENTS
This print showcases the intricate process of producing radioactive tracers at Amersham International. The image captures a moment in the preparation of technetium-99m (Tc-99m) isotope generators, which serve as vital sources for gamma ray scintigraphy in hospital nuclear medicine departments. Within the confines of a shielded facility, remote control technology enables the precise dispensing of radioactive molybdenum-99, derived from nuclear reactor fission products, into columns within these generators. The glass windows are infused with a lead compound, lending them their distinct yellow-green hue and providing essential radiation shielding. The significance lies in Tc-99m's short-lived nature; its half-life lasts only six hours. To ensure a continuous and short-term supply, an ingenious approach is employed: utilizing a generator fueled by molybdenum-99, its longer-lived parent isotope. This mesmerizing fusion of technology and processing exemplifies the careful handling required when dealing with radioactivity. It serves as a reminder of both the immense energy harnessed within this field and the industry's commitment to safety measures that protect against potential hazards. Through this remarkable snapshot captured by Science Photo Library, we gain insight into Amersham International's pivotal role in advancing nuclear medicine. This photograph encapsulates not just scientific expertise but also highlights how innovation continues to drive progress in healthcare without mentioning any commercial applications.
