Is alpha radiation emmitted by all radioactive substances?
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.
What elements are used as a shields to protect radioactive substances?
* Alpha radiation can be stopped by a sheet of card * Beta radiation can be stopped be a few inches of aluminium * Gamma radiation can be stopped by several inches of lead or many feet of concrete.
What causes radioactive things to glow?
Radioactive materials can emit radiation which can interact with nearby molecules, causing them to emit light. This phenomenon is known as Cherenkov radiation and is responsible for the glowing effect seen in some radioactive substances.
Which type of radiation is most penetrating in solid substances?
Gamma radiation is the most penetrating type of radiation in solid substances due to its highly energetic nature and ability to penetrate through thick materials. Its high penetration power makes it difficult to shield against, requiring dense materials such as lead or concrete for effective protection.
What are the types of electromagnetic radiation commonly used to identify substances?
Common types of electromagnetic radiation used to identify substances include X-rays, gamma rays, ultraviolet-visible (UV-Vis) light, and infrared (IR) radiation. Each type interacts with substances in different ways, providing valuable information about the molecular structure and composition of the material being analyzed.
How is radiation is dangerou?
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.

What is a radioactivity substances?
Substances that emit ionizing radiation
What are carcinogens and what can cause them?
Carcinogens are cancer-causing things, including some chemicals and some types of radiation. The risk for their causing cancer can be brought about by smoking, by exposure to ultraviolet radiation, nuclear radiation, or to a wide range of toxic substances.
Does toxic waste give off radiation?
What toxic waste? Some toxic waste gives off radiation, some doesn't
Give 5 examples of boidegradable substances?
some various biodegradable substances areCottonPaperWoodDead animals or plants
Which of the following substances absorbs UV radiation?
The substance that absorbs UV radiation is ozone.
What are substances that block radiation?
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.
What are some alternative options to potassium iodide for radiation protection?
Some alternative options to potassium iodide for radiation protection include Prussian blue, DTPA, and calcium. These substances can help remove radioactive particles from the body and reduce the risk of radiation exposure.
How is radiation therapy administered?
Radiation therapy is delivered via external radiation or via internal radiation therapy (the implantation/injection of radioactive substances).
Exposing certain substances to radiation is known as?
irradiation
