Substances that emit ionizing radiation
Charcoal does not block radiation. Radiation is a form of energy that can pass through materials, including charcoal. Specialized materials such as lead or concrete are typically used to block radiation effectively.
No, not all radioactive substances emit alpha radiation. Alpha radiation consists of helium nuclei (two protons and two neutrons) being emitted from the nucleus of an atom. Some radioactive substances emit alpha radiation, while others emit different types of radiation such as beta or gamma radiation.
Ultraviolet is ionising radiation. That means that it will ionise (turn into ions) some substances due to being a high energy form of electromagnetic radiation. If these 'substances' happen to be in your skin then you can start to see how UV radiation can be bad.

Radiation therapy is delivered via external radiation or via internal radiation therapy (the implantation/injection of radioactive substances).
My Astronomy professor says that we need at least 15 feet of concrete to block nuclear radiation.

Radiation
Some substances give off radiation because they are unstable and try to reach a more stable state by releasing energy in the form of radiation. This radiation could be in the form of alpha particles, beta particles, or gamma rays.
Materials such as lead, concrete, and thick metal sheets are commonly used to block electromagnetic radiation. Additionally, materials containing high amounts of copper, like copper mesh or copper foil, can also effectively block electromagnetic radiation. It is important to use materials that are thick and dense enough to provide sufficient shielding against the specific frequency of electromagnetic radiation you are trying to block.
