  1. Beta radiation consists of fast-moving electrons ejected from the nucleus of an atom. Beta radiation has a negative charge and is about 1/7000th the size of an alpha particle, so it is more penetrating. However, it can still be stopped by a small amount of shielding, such as a sheet of plastic. Gamma radiation:

    Electromagnetic radiation (EMR) consists of waves. The waves contain electric and magnetic energy. The electromagnetic spectrum (EMS) includes different types of energy waves. At one end of the spectrum, there are very low energy waves. Radio waves are an example of low energy waves. At the other end of the spectrum, there are very high energy wave...

    Radiation can be either non-ionizing or ionizing. 1. Non-ionizing radiation doesn’t have enough energy to ionize atoms or molecules. That means it can’t cause atoms to gain or lose electrons. There are several types of non-ionizing radiation. They include near ultraviolet light, visible light, infrared radiation, microwaves and radio waves. Even if...

    Particle radiation is made up of atomic or subatomic particles. These particles include protons, neutrons and electrons. They all have kinetic energy. That’s the energy is the energy an object has when it’s in motion. Both alpha particles and beta particles produce ionizing radiation. The charge they carry can remove electrons from atoms. They can ...

  2. Light does not have a charge. "Charge" is just what we call the tendency of something to affect and be affected by electromagnetic fields, which are what light is made of. The reason positive and negative charges are attracted to each other is that they both give off these fields. An electron creates an electric field that attracts positively ...

  3. Causes cell damage, radiation damage. Table 15.1 Electromagnetic Waves This table shows how each type of EM radiation is produced, how it is applied, as well as environmental and health issues associated with it. The narrow band of visible light is a combination of the colors of the rainbow.

  4. Mar 19, 2020 · The second kind of radiation is a beta particle. It's an electron that is not attached to an atom. It has a small mass and a negative charge. Tritium, which is produced by cosmic radiation in the atmosphere and exists all around us, emits beta radiation. Carbon-14, used in carbon-dating of fossils and other artifacts, also emits beta particles.

  5. Feb 22, 2024 · That is, they have neither a positive nor a negative charge. A neutron has about the same mass as a proton. Nucleus — The central part of an atom that contains protons and neutrons. The nucleus is the heaviest part of the atom. Proton — A small atomic particle, typically found within an atom's nucleus, that possesses a positive electrical ...

  7. Mar 20, 2020 · Radiation is energy given off by matter in the form of rays or high-speed particles. All matter is composed of atoms. Atoms are made up of various parts; the nucleus contains minute particles called protons and neutrons, and the atom's outer shell contains other particles called electrons. The nucleus carries a positive electrical charge, while ...
