The U.S. Million Person Study of Low-Dose-Rate Health Effects
There is a critical knowledge gap regarding the health consequences of exposure to radiation received gradually over time. While there is a plethora of studies on the risks of adverse outcomes from both acute and high-dose exposures, including the landmark study of atomic bomb survivors, these are not characteristic of the chronic exposure to low-dose radiation encountered in occupational and public settings. In addition, smaller cohorts have limited numbers leading to reduced statistical power.

This technical note models the concept of fuzziness along with the stochastic behavior of the point-kinetics neutron equation. The fuzzy stochastic model is investigated numerically by extending the Euler-Maruyama method to fuzzy form. The uncertain neutron density and delayed neutron population are obtained and compared with Monte Carlo and stochastic principal component analysis solutions. Various combinations of fuzzy parameters are considered, and the uncertain neutron density and delayed neutron population are obtained in different cases. Finally, the sensitivity of these fuzzy parameters with stochastic behavior is investigated.
