I know there are different types and levels of radiation with different affects. I read about some positive affects of ionizing radiation like :
Useful for imaging parts of the body and other objects that can not be seen normally : x-rays for bones, CAT scans for softer tissue, x-rays and gamma ray for machine parts, even neutrons for things like bomb and other carbon-based images.
Useful for sterilizing material that can't be subjected to high heat or chemicals. This includes delicate plastics and medical equipment.
Useful for killing tumors and cancers. Rapidly dividing cells are more susceptible to the effects of radiation. Cancer cells can be killed without harming surrounding tissue as much.
Whether natural or man-made, radiation can be both harmful and beneficial to the environment. The sun, for example can have positive and negative effects on plant and animal life. At low levels, radiation can be beneficial to the environment. Everything is radioactive at some level. Even humans.
This above is what I know so far and what is proven to be,but I am curious about possibility of other positive affects of radiation.Is it possible that some type of radiation in a certain level can affect human speed,thinking,senses sharpening,not to call it super power,but let just say more than normal. And also could it affect nature growth? Animals? What examples of positive affects would you like to exist,in case none of this above is possible?
