Radionuclides are purified and compounded like other drugs to form radiopharmaceuticals. Radiologic technologists and nuclear medical technologists operate sophisticated equipment to help physicians and other health practitioners diagnose and treat patients. Radiologic technologists prepare patients and operate equipment, keep patient records, and adjust and maintain equipment. They may also prepare work schedules, evaluate equipment purchases or manage a radiology department. Nuclear medicine technologists administer radiopharmaceuticals to patients, then monitor the characteristics and functions of tissues or organs in which they localize.
Abnormal areas show higher or lower concentrations of radioactivity than normal.
Some technologists may be on-call in case of emergencies. Although potential radiation hazards exist in this occupation, they have been minimized by the use of lead aprons, gloves and other shielding devices, as well as by instruments that monitor radiation exposure. Technologists wear badges that measure radiation levels in the radiation area and detailed records are kept on their cumulative lifetime dose. Meticulous personal hygiene and a fanatical regard for cleanliness and safety are a must for all healthcare workers. Patient care professionals must be sympathetic, patient and caring.
