Fundamental principle of radiotherapy with radio active-isotopes

ABSTRACT

Radiotherapy with radioactive-isotopes was used in the treating of some thyroidal diseases, malignant diseases of blood, and cancer… The efficacy of this method is depended on radiation, radiating energy, destiny of in vivo transformation of radioactive-isotopes, half-life disintegration time, and characteristics of treated cells and tissues. Author introduces some diseases treated by radiotherapy such as Basedow’s disease, simple goiter, polycythemia, and chronic disease of white blood cell… In addition author introduces some methods such as treating by radioactive colloid and radioimmunotherapy
