You mean a physical substance which could be lead or concrete.
Some ultraviolet radiation can be blocked by sunblocks and clothing. Other types of radiation such as X-Rays used in medicine can be blocked by lead.
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.
Substances that emit ionizing radiation
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.
Yes, glass can block some infrared radiation, depending on the type of glass and its thickness.
To effectively block infrared radiation, you can use materials that are opaque to infrared light, such as metal foils, certain types of glass, or specialized films designed to block infrared radiation. These materials can absorb or reflect the infrared radiation, preventing it from passing through.
Lead and concrete are effective materials for blocking gamma radiation. Lead is dense and absorbs gamma rays, while concrete provides a barrier that can block the radiation. Using a combination of lead and concrete shielding can effectively block 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.

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