By the way, the amount of "power" (Watts) emitted from all radiation and including obviously electromagnetic energy from our Sun, is roughly about, 3.86 x 10 to the power of 26 Watts per meter!! ..so add 26 zero`s to the end of that 26, and you have what is an unimaginable amount of energy coming from our Sun!!!!...And yet we are supposed to believe that a tiny thickness of aluminium will protect people leaving our atmosphere......
I'm assuming you're talking about the total emitted power of the sun, right? You do know that the Earth only receives about 1/2.2billionth of that? 3.86x10^26 * .0000000045 = 1.73*10^17 watts. But, Earth is REALLY big. It has a cross section of 127,400,000km^2, so it's about 1.36kW/m^2, or 81.65kJ/m^2. Is this a lot? Well, we need to know if this is ionizing radiation (the harmful kind), what kind of radiation it is (particles, waves, etc), what was the intensity of the radiation when hitting the hull of the craft, and then we need to know how much of it can penetrate a .75inch (minimum) hull of aluminum.
Luckily, seismometers were carried on each mission. No mission got anywhere close to deadly amounts.
Also, I invite you to read these three pages on radiation, the Van Allen Belts, and Solar Particle Radiation:
Clavius: Environment - radiation primer
Clavius: Environment - radiation and the van allen belts
Clavius: Environment - here comes the sun
