What is Radiation?

Radiation is energy that comes from asource and travels through space and

may be able to penetrate variousmaterials.Atoms that have unstable nuclei are

classified as Radioactive.

These atoms emit excess energy or massto reach stability.


4/26

Natural Types

Alpha Radiation.Beta Radiation.

Gamma Radiation.


5/26

Radiation: ITS DANGEROUS!

Radiation causes breaks between basepairs of DNA.

This causes problems in cell replicationwhich can eventually lead to cell deathor cell mutation.


6/26

Measurement of Radiation.Units.

Conventional Unit RadSI Unit Gray (Gy)

Conventional Unit Rem

Common Sources of Radiation

Natural Background: 56%Medical and Dental X rays: 41.7%

Weapons Tests Fallout: 2.2%Nuclear Power Plant Operation:0.002%

Other Sources

Any Element with an atomic numbergreater than 82 (Lead) is radioactive.

Examples: Polonium, Radon, Uranium,Radium.Space.
