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.

Fuel used in nuclear reactors contains fissile material. The fission process releases a huge amount of energy, and hence, the fissioning components must be held in a robust form capable of enduring high operating temperatures and an intense radiation environment. The shape and integrity of the fuel structures must be maintained over a period of several years within the reactor core to prevent the leakage of fission products into the reactor coolant. Further, the fuel rods must be in a nondistorted state for proper alignment in the fuel assembly to ensure proper fuel bundle power distribution. Improper core power distribution can breach the safety and operational limits on fuel and channel powers. The strategy discussed includes the methodology to verify the fuel assembly using image processing techniques. The methodology uses the Radon transform and contains four phases: image reading, preprocessing, Radon transform, and verification. The approach has been validated on 1026 fuel assemblies of a nuclear power plant, for which experimental results are shown.
