Breaking ground on a new approach to construction
The drive to Kairos Power’s reactor demonstration site in Oak Ridge, Tenn., is not only scenic—it’s historic. Nearly 85 years ago, roughly 30,000 construction workers transformed orchards and farmland into a key Manhattan Project site. Depending on your route, you may pass by one of the three gatehouses that were once military checkpoints controlling access to Atomic Energy Commission production facilities.

Dose as a function of depth in tissue has been calculated for the case of solar-flare protons incident isotropically on slab shields followed by tissue slabs. The flare used has a spectrum that is exponential in rigidity with a characteristic rigidity P0 of 80 MV. Only incident protons with energies between 0 and 400 MeV are considered. Slab thicknesses of 4 and 20 g/cm2 of aluminum are considered and a tissue thickness of 30 cm is used. In general, it is found that the secondary contribution to the dose is small unless thick shields are considered. In particular, the secondary neutrons from flare protons with energy of less than 50 MeV do not contribute appreciably to the dose in the cases considered here.
