I am so ashamed, A squid out nuked me with his chart. 90 percent just being conservative. OK I will attempt Question though,
M48 has more shielding because its armor is mostly metal versus a composite armor for M-1.
I was thinking not being a squid and all could the Japanese navy grounded one of their war ships and used the pumps on ship to pour water into the reactor.
Squids and rad workers stay in ship for shielding, just need hose.
Please I need a squid reply!!!
