Research: new results of the epidemiological study INWORKS on cancer risk among workers in the nuclear industry

 

New research results of the epidemiological study INWORKS published today reinforce the evidence of the existence of a relationship between risk of death from cancers other than leukemia and exposure to ionizing radiation. These results complete the first results of INWORKS published in June 2015 regarding leukemia risk.

 

INWORKS is an epidemiological study of mortality among workers in the nuclear industry coordinated by the International Agency for Research on Cancer (IARC www.iarc.fr) and involving IRSN, NIOSH (National Institute for Occupational Safety and Health,    www.cdc.gov/niosh) for the United States, the PHE-CRCE (Public Health England's Centre for Radiation, Chemical and Environmental Hazards www.gov.uk/government/organisations/public-health-england) for the United Kingdom, the University of North Carolina (UNC    www.unc.edu) and the Center for Research in Environmental Epidemiology (CREAL, www.creal.cat).

 

The study combines cohorts of French, American and British workers in the nuclear industry (fuel preparation, research, power generation, reprocessing of spent fuel) and monitored for external radiation exposure by wearing individual dosimeters. The population studied in INWORKS includes more than 300,000 workers, male and female employees from the mid-1940s. The French cohort of more than 59,000 individuals included in INWORKS brings together workers of AREVA NC, the CEA and EDF.

 

INWORKS aims to verify the validity of the assumptions underlying the current system of radiation protection of workers which is based on an extrapolation of knowledge of radiation-induced risks derived from the epidemiological monitoring of survivors of the atomic bombings of Hiroshima and Nagasaki. This is the largest epidemiological study ever conducted to quantify the health risks potentially associated with chronic exposure to low doses of ionizing radiation.

 

In June 2015, the first results of INWORKS reinforced the evidence of the existence of a relationship between leukemia risk and exposure to ionizing radiation (cf. our news report of 23 June 2015).

New research results published today on the website of the British Medical Journal concern the risk of death from cancers other than leukemia.
