23
Q

is a particulate form of ionizing radiation that consists of two protons and two neutrons.

24
Q
  • All of their energy is absorbed inside the body, potential causing damage to the cells.
25
Q
  • It can be stopped by paper and skin
26
Q
  • Has low penetrating ability
27
Q
  • Source is gas, Radium, Radon, Uranium, and Thorium
28
Q
  • has two types: plus and minus
29
Q
  • is an electron emitted from the nucleus of a radioactive atom. fast-moving particles in a negative electrical charge that are emitted from an atom’s nucleus during radioactive decay
30
Q
  • They travel farther in air than alpha particles
31
Q
  • stopped by a layer of clothing or by a thin layer of a substance: Aluminum
32
Q
  • Source: unstable isotopes: Carbon 14, Iodine, Strontium, Cesium
33
Q
  • usually emitted as a result of spontaneous or induced nuclear fission.
34
Q
  • Able to travel hundreds or even thousands of meters in air, they are however able to be effectively stopped if blocked by a hydrogen-richmaterial, such as concrete or water
35
Q
  • The emission of an high-energy wave from the nucleus of an atom
36
Q
  • The emission of a high energy wave from the electron cloud of an atom
37
Q

This is generally caused by energy changes in an electron, such as moving from a higher energy level to a lower one, causing the excess
