Importance of Toilet in Nuclear Medicine and Molecular Imaging Center

The practice of nuclear medicine imaging and radio-nuclide therapy involves administering a radioactive compound, which is labeled with a gamma ray or positron, or beta minus emitting radionuclide into the body of patients, resulting in radiation emissions from the patients until their radioactivity becomes negligible. These are used to provide diagnostic information in a wide range of disease states, and they range from those with short half-lives, such as 15O, 18F, 99mTc emitting photons, to relatively long-lived ones, such as 131I with both gamma rays and beta particles emitting for radio-nuclide therapy. Since the patients excrete much of the radiation via urination in the nuclear medicine facility. A special toilet (Hot or Active Toilet) for Nuclear Medicine patients is required. Because the patients excrete much of the radiation via urination, the Patient toilet should not be used for general patients, patient visitors, and hospital staff.
