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 can affect the atoms in living things, so it poses a health risk by damaging tissue and DNA in genes..Jul 13, 2021
Does radioactivity cause radiation?
Radiation is the energy or particles that are released during radioactive decay. The radioactivity of a material refers to the rate at which it emits radiation.
What are the three types of radiation from radioactivity?
Radiation is energy, in the form of particles or electromagnetic rays, released from radioactive atoms. The three most common types of radiation are alpha particles, beta particles, and gamma rays.
What type of radiation is the most radioactive?
alpha particle The first is an alpha particle. These particles consist of two protons and two neutrons and are the heaviest type of radiation particle. Many of the naturally occurring radioactive materials in the earth, like uranium and thorium, emit alpha particles.
What are the 4 types of radioactivity?
The radiation one typically encounters is one of four types: alpha radiation, beta radiation, gamma radiation, and x radiation.
What are the main causes of radioactive pollution?

What radiation causes?
Radiation is energy. It can come from unstable atoms that undergo radioactive decay, or it can be produced by machines. Radiation travels from its source in the form of energy waves or energized particles.
What are types of electromagnetic radiation?
Radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays are all types of electromagnetic radiation. Radio waves have the longest wavelength, and gamma rays have the shortest wavelength. Encyclopædia Britannica, Inc.
Which type of radiation is composed of electromagnetic waves?
In physics, electromagnetic radiation (EMR) consists of waves of the electromagnetic (EM) field, propagating through space, carrying electromagnetic radiant energy. It includes radio waves, microwaves, infrared, (visible) light, ultraviolet, X-rays, and gamma rays.
What are the causes of radiation?
Background radiation is emitted from both naturally occurring and man-made sources. Natural sources include cosmic radiation, radon, radiation in the body, solar radiation and external terrestrial radiation. Man-made forms of radiation are used in X-rays, cancer treatment, nuclear facilities and nuclear weapons.
