It depends on where the radiation is coming from.
Alpha particles are the least penetrating, having the most mass and the most charge. They can be stopped with only a few inches of air or the skin.
Beta particles are middle of the road. They have small mass, and only half the charge of an alpha particle. They can be stopped with a millimeter or so of aluminum, so they have more penetrating power.
Gamma radiation is at the high end. They are photons, with extremely low mass and no charge, so their penetrating power is highest. Often, they require massive shielding to stop them.
So, from outside the body, gamma radiation is the most dangerous.
However, if you ingest the radioactive material into your body, it can lodge in sensitive places, such as the lungs, the thyroid, the bones, nearly anywhere. In that context, alpha particles are the most dangerous, because now they have no barrier to penetration, and they have the most impact on our cells.
From weakest to strongest decay, the order is: Gamma decay - involves the emission of high-energy photons. Beta decay - involves the emission of beta particles (electrons or positrons). Alpha decay - involves the emission of alpha particles (helium nuclei).
Alpha and beta decay are often accompanied by the emission of gamma radiation. Gamma radiation is a high-energy form of electromagnetic radiation that helps to stabilize the nucleus after alpha or beta decay.
Gamma rays consist of high-energy waves and always accompany alpha and beta decay processes. They are electromagnetic radiation emitted from the nucleus of an atom during radioactive decay to achieve a more stable state.

Alpha decay: Involves the emission of an alpha particle (2 protons and 2 neutrons). Alpha particles have low penetration power but can be harmful if inhaled or ingested. Beta decay: Involves the emission of a beta particle (an electron or positron). Beta particles have higher penetration power than alpha particles. Gamma decay: Involves the emission of gamma rays, which are high-energy electromagnetic radiation. Gamma rays have the highest penetration power and are often emitted along with alpha or beta particles.

Alpha and beta decay are often accompanied by the emission of gamma radiation. Gamma radiation is a high-energy form of electromagnetic radiation that helps to stabilize the nucleus after alpha or beta decay.
There are three types: Beta decay, alpha decay, and gamma decay/gamma rays. They are all dangerous if exposed to a high amount of radioactive matter. When the radioactive isotope undergoes beta, alpha, and gamma decay, there is an emission of a beta particle, alpha particle, and gamma ray (respectively). In highly radioactive matter, there are often trillions of radioactive isotopes that emit these particles and/or rays - and they are very high-energy once emitted. However, they are only dangerous when exposed to a high amount.
alpha decay, beta decay, and gamma radiation
The four types of nuclear decay are alpha decay, beta decay, gamma decay, and neutron decay. Alpha decay involves the emission of an alpha particle, beta decay involves the emission of beta particles (either electrons or positrons), gamma decay involves the emission of gamma rays, and neutron decay involves the emission of a neutron.

Alpha, Beta, and Gamma
Beta decay is a non-example of alpha decay. Beta decay involves the emission of a beta particle (either an electron or a positron) from an unstable atomic nucleus, whereas alpha decay involves the emission of an alpha particle (helium nucleus) from a nucleus.
Alpha, Beta and Gamma. Alpha and beta are both particles, but gamma is in the form of a wave. Gamma can travel the fathest but Alpha is the most dangerous when in contact with your skin
alpha decay
Americium-241 has an alpha decay associated with gamma.
