What radiation is harmful?
Ionizing radiation is generated through nuclear reactions and can be very harmful to human health. Nuclear reactions can be naturally occurring, or artificial. There are three basic types of radiation. These include alpha, beta, and gamma radiation.
What is the most dangerous form of radiation?
Gamma raysGamma rays are the most harmful external hazard. Beta particles can partially penetrate skin, causing “beta burns”. Alpha particles cannot penetrate intact skin. Gamma and x-rays can pass through a person damaging cells in their path.
What are the 4 types of radiation?
There are four major types of radiation: alpha, beta, neutrons, and electromagnetic waves such as gamma rays. They differ in mass, energy and how deeply they penetrate people and objects.
Which of the three types of radiation is the strongest?
Gamma radiationBeta radiation is more penetrating than alpha radiation. It can pass through the skin, but it is absorbed by a few centimetres of body tissue or a few millimetres of aluminium. Gamma radiation is the most penetrating of the three radiations. It can easily penetrate body tissue.
What are the 3 types of radiation?
The three most common types of radiation are alpha particles, beta particles, and gamma rays.
