Gamma detection at Valentia, Ireland

Gamma dose rate provides a measure of the amount of energy a body receives from the surrounding gamma radiation. This radiation is always present and occurs naturally. Gamma dose rate is measured in units of microsieverts per hour (µSv/h). The normal gamma dose rates vary with local geology and typically range from 0.05 to 0.12 µSv/h. These dose rates include a component of 0.03 µSv/h due to cosmic radiation. The long term gamma background level at this location is 0.088 µSv/h. If a radioactive 'cloud' reaches Ireland, these gamma detectors will detect the associated elevated radiation levels and an alarm will be triggered
