Where do the beta, alpha and gamma radiations come from?
These radiations are released from the nucleus of an atom. Their behavior differs from one another, though all the three causes some ionization and carry some penetration power. Let’s discuss the properties of beta, alpha and gamma one by one.
What is an alpha ray?
Alpha rays are the positively charged particles. Alpha-particle is highly active and energetic helium atom that contains two neutrons and protons. These particles have the minimum penetration power and highest ionization power. They can cause serious damage if get into the body due to their high ionization power. They are capable of ionizing numerous atoms by a short distance. It is due to the fact that the radioactive substances that release alpha particles are required to be handled after wearing rubber gloves.
What is the electron that is released by the nucleus at a rapid pace?
Beta Rays. Beta particles are extremely energetic electrons that are liberated from the inner nucleus. They bear negligible mass and carry the negative charge. A neutron in the nucleus splits into a proton and an electron on the emission of a beta particle. Hence, it is the electron that is emitted by the nucleus at a rapid pace.
Why are alpha particles dangerous?
They are capable of ionizing numerous atoms by a short distance. It is due to the fact that the radioactive substances that release alpha particles are required to be handled after wearing rubber gloves.

What is the alpha radiation?
Alpha radiation consist of alpha particles, that are energetic nuclei of helium. The production of alpha particles is termed alpha decay. Alpha particles consist of two protons and two neutrons bound together into a particle identical to a helium nucleus. Alpha particles are relatively large and carry a double positive charge.
Where do gamma rays come from?
It is a part of our natural world that has been here since the birth of our planet. Natural sources of gamma rays on Earth are, among other things, gamma rays from naturally occurring radionuclides, particularly potassium-40. Potassium-40 is a radioactive isotope of potassium that has a very long half-life of 1.251×10 9 years (comparable to the age of Earth). This isotope can be found in soil, water also in meat and bananas. This is not the only example of a natural source of gamma rays.
What is the process of gamma rays?
Gamma rays are emitted by unstable nuclei in their transition from a high-energy state to a lower state known as gamma decay. In most practical laboratory sources, the excited nuclear states are created in the decay of a parent radionuclide. Therefore a gamma decay typically accompanies other forms of decay, such as alpha or beta decay.

Why is the radiation frequency important?
The radiation frequency is key parameter of all photons, because it determines the energy of a photon. Photons are categorized according to the energies from low-energy radio waves and infrared radiation, through visible light, to high-energy X-rays and gamma rays.
Where do gamma rays come from?
X-rays and gamma rays have the same basic properties but come from different parts of the atom. X-rays are emitted from processes outside the nucleus, but gamma rays originate inside the nucleus. They also are generally lower in energy and, therefore less penetrating than gamma rays.
How do gamma rays affect DNA?
Gamma rays have so much penetrating power that several inches of a dense material like lead, or even a few feet of concrete may be required to stop them. Gamma rays can pass completely through the human body; as they pass through, they can cause ionizations that damage tissue and DNA.

Radioactive elements emit ionizing radiation as their atoms undergo radioactive decay. Radioactive decay is the emission of energy in the form of ionizing radiation ionizing radiation Radiation with so much energy it can knock electrons out of atoms.
Why are beta particles less damaging to DNA?
Beta particles are more penetrating than alpha particles, but are less damaging to living tissue and DNA because the ionizations they produce are more widely spaced. They travel farther in air than alpha particles, but can be stopped by a layer of clothing or by a thin layer of a substance such as aluminum.
What are the two types of radiation?
There are two kinds of radiation: non-ionizing radiation and ionizing radiation . Non-ionizing radi ation has enough energy to move atoms in a molecule around or cause them to vibrate, but not enough to remove electrons from atoms.
