Question

What are the various uses of radioactivity in healthcare? What are the future trends in healthcare with respect to the use of radioactivity?

Answer 1

the trend is positive correlation with time

Answer 2

Sterilization of medical instruments and food is another common application of radiation. By subjecting the instruments and food to concentrated beams of radiation, we can kill microorganisms that cause contamination and disease. Because this is done with high energy radiation sources using electromagnetic energy, there is no fear of residual radiation. Also, the instruments and food may be handled without fear of radiation poisoning.
I think this field will be expanding - but instead of expansion in volume more toward precision-expansion.
**further knowladge-
Radiation sources are extremely important to the manufacturing industries throughout the world. They are commonly employed by nondestructive testing personnel to monitor materials and processes in the making of the products we see and use every day. Trained technicians use radiography to image materials and products much like a dentist uses radiation to x-ray your teeth for cavities. There are many industrial applications that rely on radioactivity to assist in determining if the material or product is internally sound and fit for its application.


Radiation is simply a type of energy; the most familiar form of radiation is visible light (like that produced from the sun or a light bulb). Other forms, like X-rays and gamma rays, are employed in a number of beneficial applications, including medicine. Natural radiation exposure comes from the earth (rocks, soil) and outer space (cosmic rays). A small amount of radioactive material even exists naturally in our bodies. Every year, each person is exposed to this natural radiation and a variety of other sources, including household smoke detectors and color television sets. Air travel increases exposure to cosmic radiation due to the higher altitudes (less atmospheric shielding).
