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.

Discussed are the advantages of using fusion neutrons for breeding special nuclear materials and tritium. Monte Carlo calculations were used to identify both fissionable and nonfissionable materials that multiply neutrons and increase breeding ratios. Fissionable multipliers also greatly multiply the neutron energy. A generic blanket design that utilizes 238U as a neutron multiplier is decribed and compared to an ideal infinite-medium blanket. Time-dependent calculations show gradual improvement of performance during the lifetime of the blanket. The blanket analyzed here is compatible with a reaction chamber that uses high velocity lithium, held on the wall by centrifugal acceleration, to protect the wall from pellet explosions.
