Ultraviolet radiation

Ultraviolet (UV) radiation is an ionising radiation. Exposure to it correlates to an incidence of skin cancer. UV light can penetrate the skin and causes mutations in the DNA of skin cells which could cause them to divide uncontrollably leading to a tumour.

It is important if you are exposed to sunlight to:

  • avoid sunburn as this is an indication that your skin has been damaged by the sun
  • use a broad-spectrum UVA/UVB sunscreen
  • wear a broad-brimmed hat
  • wear UV-blocking sunglasses

These protective measures will prevent UV damage to the skin and reduce the risk of developing skin cancer.
