The data suggest that a relationship between nuclear emissions and adverse health effects exists, especially since fetuses and newborns are most sensitive to radiation. Because Rancho Seco released low levels of radionuclides into the local environment, the issue of health effects of prolonged, low-dose radiation exposure is raised. The matter becomes increasingly important as operators of several dozen aging U.S. reactors must soon decide whether to extend their operating licenses. Utilities running these units must soon decide whether to apply to the U.S. Nuclear Regulatory Commission for a new operating license or to close reactors. To date, the principal issues associated with reactor closings have been waste management and plant decommissioning.
Little consideration is given to health status among local residents.
The fetus and infant are most susceptible to effects of radiation and other toxic chemicals. The developing infant is similarly susceptible to cellular and metabolic damage. Five of the 12 closed reactors are in areas at least 70 miles from any other nuclear power plant. No other nuclear reactor lies within 200 miles. The opening of Rancho Seco corresponds with an increase of local in vivo radioactivity.
