Gamma rays (γ) are an energetic form of electromagnetic radiation usually produced by radioactivity or other nuclear reactions. Gamma rays are more penetrating than either alpha or beta rays. |
|
Shielding for γ rays requires large amounts of mass. Shields that reduce gammay ray intensity by 50% include 1cm (0.4 inches) of lead, 6cm (2.4 inches) of concrete or 9cm (3.6 inches) of packed dirt. |

Gamma rays (γ) are an energetic form of electromagnetic radiation usually produced by radioactivity. Gamma rays are more penetrating than either alpha or beta rays. They can pass through a centimeter of lead and only be reduced in intensity by 50%, which means that gamma rays are very difficult and expensive to protect against. |

Gamma rays from nuclear fallout would probably cause the largest number of casualties in a nuclear war. An effective fallout shelter reduces human exposure at least 1000 times. |
|
Gama rays are less ionising than either alpha or beta rays. However reducing human danger requires thicker shielding. They produce damage similar to that caused by X-rays such as burns, cancer, and genetic mutations. |
