Alpha radiation cannot get pass through our body as it cannot penetrate through things. Beta can penetrate through things better than alpha. So if alpha is inside our body then it cannot get outside our body and therefore it becomes dangerous.

Is there more severe radiation than gamma?

It depends on the strength of the active source. Alpha radiation is dangerous if it gets inside your body, gamma will penetrate your clothing and body if energetic enough, so it's difficult to give an answer that covers all cases. Health physicists have to consider each type of radiation on its merits.

Why workers work far from the source of radiation?

Radiation is dangerous ... Too much kills but even small amounts may eventually cause cancer. Radiation levels decrease as does gravity with the square of the distance from the source. At twice the distance, the rad level becomes 1/4 th as much.

What are the negative effects of alpha radiation?

Alpha radiation can be harmful if ingested or inhaled, as it can damage cells and DNA, leading to an increased risk of cancer. However, alpha particles can be stopped by a sheet of paper or human skin, so they are not as dangerous as other types of radiation unless the source is inside the body.

Why is it more dangerous to be exposed to weak x-ray source than to a strong infrared source?
