It is true you can't filter or metabolize radiation through blood or bone marrow transfusions but that is just the in universe explanation so just deal with it. Though there is a way our cells could one day repair the damage caused by radiation way more efficient than it does today I won't explain it I'll just link the article http://goo.gl/oCNfyl but I'll tell you this if The 100 writers read this beforehand it would explain why the Sky People are generically engineered because I'm sure this would be first tested on Astronauts giving their descendants immunity and would make more sense how the Mountain Men could achieve immunity by dissecting and harvesting them. To explain why Grounders are resistant is simple as another person posted above over time some people would become more resistant but remember not all Grounders are and plenty stil have children with deformities but they usually kill them before they grow up this is why most Grounders we see have none in fact that part is the most accurate part of living so long in radiation that the show gets right. There are real life examples of this just look up some cities the USSR use to test radiation on for decades  and how it still lingers there. Today those people still live there in fact some are perfectly fine while others have deformities or health issues. So to explain to someone who said it would take a lot longer for the Grounders to become resistant not true to be 100% yes it would but the Grounders are not 100% immune to radiation just more resistant than the Mountain Men.
