We develop policy to help respond to environmental threats and hazards to human health including chemicals and radiation.

Heatwave information

Heat can affect anyone, but some people run a greater risk of serious harm. These include:

  • older people
  • babies and young children
  • people with mental health problems
  • people on certain medication
  • people with a serious chronic condition, particularly breathing or heart problems
  • people who already have a high temperature from an infection
  • people who use alcohol or illicit drugs
  • people with mobility problems
  • people who are physically active, like manual workers and sportsmen and women.

Radiation and Health

The Welsh Government wants to reduce the risks to health from exposure to ionising radiation and non-ionising radiation.

This could include radon gas, electromagnetic fields, sunlight (UV radiation), artificial tanning devices and radiofrequencies.

Carbon monoxide

Carbon monoxide in the home is responsible for a considerable number of deaths each year and for many more cases of sub-lethal poisonings.
