PPT-RADIATION EFFECT Radiation biology

Radiation biology is the study of the action of ionizing radiation on living organisms The action is very complex involving physics chemistry and biology Different types of ionizing radiation .

Ultraviolet light can be used to inactivate many types of organisms, including viruses, but it is currently known that UV light only works on surfaces or clear liquids such as water. . UV light radiation has been used for many years in pharmaceutical, electronic, and aquaculture industries as a disinfection medium. . Dr. . Ramesh. . Tiwary. Assistant Professor. Deptt. . of Vet.
