How does a substance become radioactive?
A number of elements have atoms or nuclei which are unstable and consequently split up to form smaller atoms.
A substance is said to be radioactive if it contains unstable nuclei and is able to naturally release energy in the process of shedding high speed charged particles, in an attempt to reach a stable state..
Can a person become radioactive?
If someone has been exposed to radiation, do they carry the radiation in them or is it the contamination—dust, etc. … There is one radiation, well-known but less common than those mentioned above, that is capable of inducing radioactivity in an irradiated person or object; that is neutron radiation.

How long do things stay radioactive?
Radioactive isotopes eventually decay, or disintegrate, to harmless materials. Some isotopes decay in hours or even minutes, but others decay very slowly. Strontium-90 and cesium-137 have half-lives of about 30 years (half the radioactivity will decay in 30 years).
What are the three causes of radioactivity?
What causes atoms to be radioactive? Atoms found in nature are either stable or unstable. An atom is stable if the forces among the particles that makeup the nucleus are balanced. An atom is unstable (radioactive) if these forces are unbalanced; if the nucleus has an excess of internal energy.
Is Radioactive dangerous?
Low levels of radiation are not dangerous, but medium levels can lead to sickness, headaches, vomiting and a fever. High levels can kill you by causing damage to your internal organs. It’s difficult to treat high radiation exposure. Exposure to radiation over a long time can cause cancer.
What does it mean to be radioactive?
Definition of radioactivity. : the property possessed by some elements (such as uranium) or isotopes (such as carbon 14) of spontaneously emitting energetic particles (such as electrons or alpha particles) by the disintegration of their atomic nuclei also : the rays emitted.
Does an irradiated object become radioactive?
Being irradiated can affect the properties of the object (like killing germs in food) but doesn’t make the object radioactive. Additionally, irradiated objects and radioactive objects tend to serve different purposes.
Are bananas radioactive?
Bananas are slightly radioactive because they contain potassium and potassium decays. Potassium is a necessary substance for healthy operation of your body. You would have to eat a LOT of bananas just to compete with the natural potassium dose of your body.
How do you wash off radiation?
2b. Wash yourself off.Take a warm shower and gently wash yourself with lots of soap. Do not scald, scrub, or scratch your skin. … Wash your hair with shampoo or soap. … Keep cuts and abrasions covered when washing to keep from getting radioactive material in open wounds.
Did they bury Chernobyl victims in concrete?
Like the other ARS casualties, he was allegedly buried in a sealed zinc coffin and in a concrete shielding, due to fears that radioactivity could leak out and contaminate the grounds.
What are the 3 types of radioactivity?
The three most common types of radiation are alpha particles, beta particles, and gamma rays.
