Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which one is radioactive in nature?
A
Helium
B
Tritium
C
Deuterium
D
Heavy hydrogen
Explanation: 

Detailed explanation-1: -Small traces of hydrogen 3 or tritium occurs in nature due to the synergy of cosmic rays with atmospheric gases. They are also released in a small amount at the time of nuclear weapons tests. It is radioactive, it decays into helium 3 through beta decay.

Detailed explanation-2: -Tritium is a radioactive form, or “isotope”, of hydrogen. It has two neutrons where regular hydrogen does not have any, which makes tritium unstable and therefore radioactive. It is produced naturally from interactions of cosmic rays with gases in the upper atmosphere.

Detailed explanation-3: -Ex: Uranium, thorium, etc are the atoms which is radioactive in nature because of its instability.

Detailed explanation-4: -Tritium is a relatively weak source of beta radiation, which itself is too weak to penetrate the skin. However, it can increase the risk of cancer if consumed in extremely large quantities. Tritium can enter the body through inhalation, ingestion or absorption through the skin.

Detailed explanation-5: -Although deuterium is an isotope, is not radioactive. Both deuterium and protium are stable isotopes of hydrogen. Ordinary water and heavy water made with deuterium are similarly stable. Tritium is radioactive.
