Health Effects - Genetic Mutation

Radiation affects people by depositing energy in body tissue, which can cause cell damage or cell death. In some cases, there may be no noticeable effect. In other cases, the cell may survive but become temporarily or permanently abnormal. Additionally, an abnormal cell may become malignant. Both large and small doses of radiation can cause cellular damage.

The extent of the damage depends on these factors:

• The total amount of energy absorbed
• The time period and dose rate of the exposure
• The particular organs exposed

Damage to genetic material in reproductive cells can cause genetic mutations that can be passed on to future generations. In rare instances where there is a large amount of radiation exposure, sickness or even death can occur in a matter of hours or days.
