The group is led by Professor Elisabeth Cardis. Researches working in the group include Magda Bosch de Basea (EPI-CT), Gemma Castaño (Mobi-Kids, GERoNiMO), James Grellier (Alpha-Risk, INT-Thyr, GERoNiMO), Elisa Pasqual (ProCardio, Spain-CCSS, OPERRA), Michelle Turner (INTEROCC, GERoNiMO, EPILYMPH) and Javier Vila (INTEROCC, GERoNiMO).
Radiation is the process by which energy—in the form of waves or particles—moves through media which are not required for its propagation. Radiation is classified as either ionizing or non-ionising depending on whether or not it has sufficient energy to cause atomic changes in the matter through which it passes. Both kinds of radiation are found in the environment and exposures to them may occur as a result of both natural and anthropogenic processes. Increases in the application of non-ionising radiation as a means of transmitting data—for example, in mobile communications—have raised concerns about potential risks to health. Similarly, new ionising radiation imaging and treatment modalities are increasingly used in both diagnostic and therapeutic procedures in many areas of medicine, and understanding potential risks to the health of both patients and medical staff are paramount in maximising the efficacy of treatments while ensuring their safety. Understanding potential risks associated with occupational and accidental exposures to ionizing radiation in relation to the nuclear industry is also key to radiation protection and public health.
Exposure to non-ionising radiation from a variety of sources has been potentially associated with a number of health outcomes including some cancers, but mechanisms explaining such associations are largely missing. Epidemiological research continues to contribute to exploring how non-ionising radiation might affect human systems. Exposure to ionizing radiation has been conclusively linked to the risk of cancer and other health outcomes in a variety of studies. However, the nature of such risks at low doses is much less well understood.
The overall objective of the Radiation Programme is to better understand the potential risks associated exposure to radiation. Ultimately this aim serves the radiation protection of the general public, patients and those exposed in their work, and informing policy to achieve this goal. In addition, our research contributes to better understanding the processes by which radiation affects human physiology and human health.
