WebThe 131 I isotope is also used as a radioactive label for certain radiopharmaceutical therapies, e.g. 131 I-metaiodobenzylguanidine ( 131 I-MIBG) for treating pheochromocytoma and neuroblastoma. Iodine-131 also emits high energy gamma radiation (364 keV; 10%) that can be used for imaging [ 18 E]. WebApril 3rd, 2015 By Mirion Technologies. Ionizing radiation takes a few forms: Alpha, beta, and neutron particles, and gamma and X-rays. All types are caused by unstable atoms, which have either an excess of energy or mass (or both). In order to reach a stable state, they must release that extra energy or mass in the form of radiation.
