Reply to comment by Bewaretheicespiders in Investigations reveal more evidence that Mimas is a stealth ocean world by entered_bubble_50

Earth background is .3uSv/hr = .00003rad/hr.... rads halved by 7cm of h2o shielding... Surface rads at 360 rads/hr... 360*(.5)^x = 3E-5 -> 3E-5/360=.5^x

Log(12E6^-1) / Log(.5) = x

x = ~23.5

23.5 * .07m = ~ 1.65 meters of ice.

So TLDM : If you stay under about 1.7 meters of ice (maybe a little more due to density concerns) you should only experience normal earth background radiation... on paper.

I only did the math in my head...but it appears to check out.

Yeah same. This one was actually kinda hard, took me like 4 or 5 seconds to calculate.

Napkins are where real math gets done, for everything else there's CAD.

I’m not taking about the quality of it i’m talking about the complexity of it some of us only just barely finished algebra

Much like my wife tells me, "It's bold that you think I finished at all"

Interestingly, the hypothetical ocean would be deeper under the ice than that, implying a much lower background radiation exposure than on Earth.

Which suggests a lower mutation rate for any life forms that live there. Although of course that might depend on whether they evolved to be more mutation prone as a meta-evolutionary strategy....
