Because in the body alpha particles interact directly with the organism cells.
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.
Alpha and beta radiation can be more dangerous from sources inside the body because when emitted internally, they can directly damage nearby tissues and organs. External sources of alpha and beta radiation have less chance of penetrating the body to reach vital organs. Additionally, internal sources can prolong exposure and increase the risk of damage over time.
Alpha, from outside the body, because alpha is stopped by the skin, a sheet of paper, or a few inches of air. From inside the body, however, alpha is one of the most dangerous forms of radiation.
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 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.
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.

Any electromagnetic radiation can be dangerous. Alpha waves are higher on the radiation scale than x-rays so yes, they are dangerous.

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.
Generally no radiation is safe. You cannot "inject" radiation into anything because it is the product of various unstable nuclei decaying. Alpha radiation is much more ionising than gamma, but much less penetrating than it. That makes it more dangerous if it is inside your body; it can be stopped by skin. Therefore you would have to swallow a sample of a radioactive material. However, gamma radiation is always emitted together with alpha or beta radiation.
Alpha radiation is the most dangerous type of radiation when inhaled or swallowed, as it is highly ionizing and can cause significant damage to tissues. Its low penetration ability allows it to come in direct contact with internal organs, increasing its harmful effects.
Alpha radiation releases a large amount of energy in a short distance, which can cause significant damage to surrounding tissues. If alpha-emitting radioactive material is ingested or inhaled, it can come into direct contact with sensitive internal tissues, leading to cell damage and potential long-term health effects such as cancer.
