Alpha Particles
Alpha particles have a low penetration power and can be stopped by a sheet of paper or even human skin. However, if alpha-emitting radionuclides are ingested, inhaled, or enter the body through a wound, they can cause significant damage to cells and tissues.
Gamma radiation, X Rays
Radioactive elements emitting alpha particles are more dangerous outside the body because alpha particles can travel only a short distance in air but can cause significant damage if they enter the body through inhalation or ingestion. Inside the body, alpha particles have a higher chance of being stopped by tissue before causing harm due to the limited range.
Because in the body alpha particles interact directly with the organism cells.
Plutonium-239 is a radioactive particle that is harmful to human beings due to its high toxicity and ability to emit high-energy alpha particles, which can damage cells and cause long-term health effects such as cancer and organ failure if ingested or inhaled.
Alpha particles are actually electron-less helium nuclei versus beta particles which are actually electrons, which are much smaller than alpha particles. Therefore, alpha particles' penetrating strength is much smaller than beta particles (a sheet of paper versus a wooden board). Therefore, beta particles will penetrate more into a human body and will do more damage than alpha particles which are usually stopped at the skin.
1. Alpha Particles are the least penetrating, but do a great deal of radiation damage on the surface of what they hit.2. Beta Particles penetrate to a certain extent depending on their energy.3. Gamma Rays penetrate the most, and a Gamma source requires heavy (lead, etc.) shielding.
Because in the body alpha particles interact directly with the organism cells.
Alpha radiation is more harmful inside the body because alpha particles have a high ionizing power and are more likely to interact with cells and tissues, causing damage to DNA. When emitted outside the body, alpha particles can be stopped by skin or clothing and are less likely to penetrate deeply into tissues where they can cause harm.
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.
If Alpha Particles are inhaled, ingested (swallowed), or absorbed into the blood stream, alpha radiation is exposed to sensitive living tissue. The biological damage results in the increased chances of cancer, particularly lung cancer which is caused when alpha emitters are inhaled.
