Dear Nathan Jones:
"Nathan Jones" wrote in message ... The 1969 - 1972 Apollo missions occured during a sunspot maxima period. It was known at the time that on any particular day there were on average to be expected (during the maxima years) about 15 detectable solar flares that would be headed for Earth and if we take them all to be low energy flares of about 2.5 rem each then that would mean that the Apollo astronauts would have been exposed to 375 rem each day. The maximum permissible dose for Joe public is 0.5 rem per year. Go figure! "Would be headed for Earth". Didn't. "Permissible dose". Maybe we should arrest them? Disinformation at its best. David A.

The maximum permissible dose for Joe public is 0.5 rem per year. Go figure! The actual doses received by the astronauts are a matter of public record, although that's also part of the global conspiracy, of course. I'm fairly sure that your figures are incorrect, as you don't provide any references, but I can't be bothered to look up the real ones. The burden of proof is on you, as the accuser. I will note that everyone knows they were lucky. A big flare could have killed them on the Moon (the CM had sufficient shielding). But were there any major flares that directed material toward the Earth during the relevant times? Something else for you to look up. -- Rabbit arithmetic - 1 plus 1 equals 10 Remove spam and invalid from address to reply. |

Maybe we should arrest them? Disinformation at its best. Definitely. The permissile public dose is base on risk assessment - mainly cancer induction. Radiation workers are allowed to occationaly acquire up to .05 Gy (5 rem) in a year. But immediate effects (e.g. radiation sickness) generally start around a single dose of .5 Gy. However, the August '72 flare would have jeoparized any Apollo mission at the time, as they would have received something like 5-10 Gy (500-1000 rem) within a few hours. 5 Gy is a potentially lethal dose if you don't come under medical care soon. James Michener used this scenario for a fictious Apollo 18 mission. I wonder what doses last week's eruptions would have given ... |
