Ionising nuclear radiation can cause a range of harmful effects on living organisms. These include:
- Cell Death: High doses of radiation can damage cells to the point where they are unable to function and eventually die. This can occur directly through DNA damage or indirectly through the disruption of cellular processes.
- Mutations: Radiation can alter the genetic material (DNA) within cells. These alterations, known as mutations, can be harmful, leading to genetic disorders or an increased risk of diseases.
- Cancer: Mutations caused by radiation can lead to uncontrolled cell growth and the development of cancerous tumours. The increased risk of cancer is a long-term effect of exposure to ionising radiation.
- Acute Radiation Syndrome (ARS): Exposure to very high doses of radiation within a short period can cause ARS, leading to a range of symptoms including nausea, vomiting, hair loss, and damage to the bone marrow and immune system. This can be fatal.
