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.

Recently, oscillating high-speed slab jets, or liquid sheets, have been proposed for shielding the first walls of inertial fusion energy (IFE) reactor chambers from damaging X-rays, neutrons and ions. The near-field dynamics of obliquely oscillating turbulent liquid sheets were investigated in scaled experiments. Results are presented for sheets at Reynolds numbers up to 37000 oscillated along various directions at frequencies from 0 to 11 Hz and amplitudes up to half the nozzle thickness (0.5δ). Data on maximum trajectories of oscillating sheets and growth rates of stationary sheets are presented for distances up to 90δ downstream of the nozzle exit. A model for predicting the maximum trajectory is presented. The bulk of the experimental data are in reasonable agreement with this model. These results can be used to provide design guidelines for thick liquid protection.
