Chapter 25 – Types of Radiation 1. Alpha Radiation Alpha decay
... Positron decay is the mirror image of beta decay and can be described as: a. Something inside the nucleus breaks down causing a proton to become a neutron. b. It emits a positron which goes zooming off. c. The atomic number goes down by one and the mass number remains unchanged. Here is a typical po ...

... Units of radiation include • Curie - measures activity as the number of atoms that decay in 1 second. • rad (radiation absorbed dose) - measures the radiation absorbed by the tissues of the body. • rem (radiation equivalent) - measures the biological damage caused by different types of radiation. ...

Background radiation
Background radiation is the ubiquitous ionizing radiation that people on the planet Earth are exposed to, including natural and artificial sources.Both natural and artificial background radiation varies depending on location and altitude.
