INFLUENCE OF NUCLEAR FUEL CYCLE NUCLEAR AND RADIOACTIVE FACILITIES ON MORTALITY DUE TO CANCER IN PERSONS LIVING IN THE VICINITY OF SUCH FACILITIES IN SPAIN
1. INTRODUCTION AND OBJECTIVES
2. MATERIAL AND METHODS
2.1
Design of the epidemiological study
Selection of municipal areas around nuclear facilities and control municipalities

Selection of municipalities in two areas with different exposure to natural radiation
Causes to be studied

2.2
Estimate of exposure to ionising radiations in the vicinity of the facilities studied
Selection of an exposure indicator for each municipality included within the scope of the study
Estimate of artificial radiation doses to the members of the public in the vicinity of nuclear power plants and fuel cycle facilities and of those due to natural radiation
Criteria for the establishment of cut‐off points
2.3
Analysis of mortality

5. CONCLUSIONS
Note 1. This report has been drawn up by the Carlos III Institute of Health (ISCIII) and the Nuclear Safety Council (CSN), each within its respective realm of competence and function as regards the issues dealt with. The CSN is responsible for all aspects relating to the reconstruction of the history of exposure of the population to ionising radiations arising from the operation of the facilities and to those of natural origin. The ISCIII is responsible for the design and performance of all aspects of the cancer mortality study and for drawing up all the sections of the report referring to this issue.
