Analyse the benefits and problems associated with the use of Radioisotopes in identified industries

Radioisotopes allow treatment and diagnosis of medical illnesses without the cost and trauma of open surgery (which carries risks like infection, accidents, and long recovery periods). The use of Tc-99m produces hot-spot images, which reveal early signs of disease and map how organs are functioning. The low energy gamma radiation it emits, the small dose in which it's injected and it a short half-life (6hours), minimises damage to tissues.

Those with longer half-lives are particularly problematic. Strontium-90 (half life: 28 years) is used in thickness gauges in industry to monitor and control the thickness of materials such as steel sheets, paper, foil, and plastic film. It decays to yttrium-90, which emits high-energy beta-particles. This imposes greater health risks if Sr-90 is released to the environment
