What can stop alpha radiation?

Answer 1

Alpha particles have little ability to penetrate. They are generally stopped by a few inches of air, or a piece of paper. In general, if they strike a person's body, they are stopped by the outermost layer of skin, which is mostly made up of dead cells. If they are emitted inside a person's body, however, the first cells they hit are likely to be living. So the protection from alpha particles consists primarily of being careful not to ingest or breath anything that can give them off.

The commonest source of alpha particles that cause problems is radon gas, which is often a problem in the basements of buildings, rooms with floors that contact the earth, and in well water. If there is any doubt about the presence of radon, it is wise to test the air. Many hardware stores have kits, they can be purchased online, and a variety of companies perform service. Remediation can be done on most buildings.

Some people work in environments where dust of alpha emitting materials could be breathed in or ingested. Precautions vary depending on the materials, but anyone who could conceivably be exposed should be instructed as to safety.

Answer 2

Alpha radiation can be stopped or absorbed by a piece of paper or clothing, a few centimeters of air, or even the outer layer of dead skin cells on the human body. This type of radiation is relatively low in energy and has a short range, making it easy to block with simple materials.

Answer 3

Alpha radiation has very low penetrating power. Even a sheet of paper is enough to stop most alpha rays.

However that is why they are the most dangerous to the unprotected human, since the particles are stopped by paper they hit our skin and do not pass through which is radiation which can result in mutations to the cells.

AS far as i know alpha radiation can't cause damage to the skin definitly no mutation to the cells

Answer 4

Alpha radiation comprises of heavy positively charged paricles and they are easily stopped by clothing or a few mm of paper. Hence they do not harm as an external radiation hazard. But if these particles are ingested by inhalation or through mouth, they are very harmful.

Beta radiation are electrons which are comparativel lighter particles and they can be stopped by a few mms of plastic. Plastic shields like acrylic is preferred to metallic shields as the electrons interact with heavy metals to produce x-rays called Bremmstrahlung.

Gamma rays are highly penetrating and they are the major exyternal hazard. You have to use the principle of time - distance - shielding to protect yourself from gamma rays. Spend as little time as possible in the vicinity of gamma rays, keep a as large a distance as possible from a gamma source and use a heavy metal or high density object as shield between you and the source.

Answer 5

alpaha radiation can possibilt stopped by paper

Answer 6

Quite easily. It can only travel a few cms in air and it's not very penetrating so it can be stopped by a piece of paper or a layer of skin so it can't penetrate the body.

Answer 7

alpha particles can be blocked by plastic while gamma rays can be stopped by lead.

Answer 8

You can stop Beta radiation with a few millimeters of aluminum.

Answer 9

Adequate shielding and cooling of nuclear fissile material.

Maintaining quantities of nuclear material in quantities that remain below the levels of critical mass.

Answer 10

use lead or just run for it
