AI Thread Summary
Former President Jimmy Carter, nearing the end of his life at 98, was an original US Navy nuclear engineer who played a crucial role in extracting the first melted core from a Canadian reactor over 70 years ago. During this operation, he entered a highly radioactive "dead zone," resulting in him experiencing radioactive contamination for six months. His exposure was estimated to be about 1000 times the current safety limits. While radiation damage is probabilistic and varies among individuals, it highlights the inherent risks associated with nuclear engineering. The discussion underscores the complexities of radiation exposure and its long-term effects on health.

Former USA President Jimmy Carter seems to be near the end of his 98 years, and was one of the original US Navy nuclear engineers. Over 70 years ago, he led a team that extracted out the world's first melted down core out of a Canadian reactor, himself going 90 seconds into the "dead zone" - and had radioactive urine for 6 months afterwards. It is estimated that he and his team got a dousing about 1000X as much as is allowed under today's protocols. Besides the risk of death, there was a risk that we would be infertile (4 children later, obviously that did not happen).

Radiation damage is a probabilistic event so a single case does not constitute proof for changing of standards.
Everyone is exposed to radiation everyday and many survive. Some do not.
 

Thread 'Energy Spectrum Attenuation'

Hello, I'm currently trying to compare theoretical results with an MCNP simulation. I'm using two discrete sets of data, intensity (probability) and linear attenuation coefficient, both functions of energy, to produce an attenuated energy spectrum after x-rays have passed through a thin layer of lead. I've been running through the calculations and I'm getting a higher average attenuated energy (~74 keV) than initial average energy (~33 keV). My guess is I'm doing something wrong somewhere...
