How much radiation does uranium 238 emit
WebWhat is uranium enrichment and why is it important to nuclear weapons? Enrichment removes unwanted uranium-238, making the concentration of uranium-235 atoms higher.It takes much more work to enrich uranium to 3-5% uranium-235 (typical power reactor fuel), than it does to further enrich uranium from 3-5% to 90% uranium-235 (weapons-grade … Webstandard (a pressurized ion chamber), the detector overresponds by as much as a factor of two where the uranium decay series is of concern. Our starting factor is 20 μR. h-1 divided by a factor of 2, so we start with 10 μR h-1. The exposure rate at the surface of an infinitely thick slab of soil with a uranium‐238 concentration of 3.7 × 10-2
