| Apr 9, 2017 at 21:51 | comment | added | Thorsten S. | @JoeKissling Thanks for pointing out the calculator. For 0.4 µS/hr (natural background radiation) as penetration and 10 S/hr contamination I get also 0.9 m of concrete, so I will adjust the value. Still I would advise to be cautious because the initial explosion will create a strong neutron flux which is far more penetrating than the gamma radiation, so I would err on the side of caution. | |
