WebThe tracers help locate the created fractures. Where there is a blockage the activity of the radiation will be highest due to collection of blood. Doctors may use radioactive chemicals called tracers for medical imaging. Basic safety precautions such as wearing goggles and washing hands after using a radioactive source should be taken. WebOne of the more common uses is as a tracer in which a radioisotope, such as technetium-99m, is taken orally or is injected or is inhaled into the body. The radioisotope then circulates through the body or is taken up only by certain tissues. Its distribution can be tracked according to the radiation it gives off. bottled up tamarinfrog
