Gamma rays, just like (visible) light rays are a form of electromagnetic radiation. Gamma rays have a much shorter wavelength (and thus more energy) than visible light, which is why they are much more dangerous to human beings (e.g. they may cause cancer).
alpha radiation is more dangerous than beta or gamma if ingested or inhaled because its power to ionize (or to disrupt atoms) is 20x than that of beta and gamma. but if the source is outside the body or at a distance gamma radiation is much dangerous because it could penetrate thick walls.
Usually for killing cancerous tumors, as in radiotherapy. Sometimes also for medical imaging, as in a gamma camera. Generally, Gamma rays are dangerous to living tissue.
Gamma Rays
While we are all exposed to them a little form rocks and from outer space, they are NOT used in everyday life. Gamma rays are dangerous.
Yes, of course.
Externally, gamma radiation is dangerous because it can penetrate the body. Alpha is most dangerous if ingested.

An improved , more accurate type of X-ray , but more dangerous , as it can cause skin cancer .

X-rays have lower energy, though they are both dangerous.
Gamma Rays
No. Gamma rays are extremely dangerous to humans and can cause death.
Gamma rays are the most penetration rays because of its shortest wave length...
Gamma Rays can pass straight through human tissue and are therefore highly dangerous. The only time you are likely to use Gamma rays is in scientific research.
