So, I haven't written a proper scientific entry on the topic yet, but this is how I see Mori-type chuubanite affecting one's lifespan.
Basically, Mori-type chuubanite makes all organics it affects change to be tougher and harder. The most obvious change is in the bones, but that happens to all the other cells as well, which results in them degrading and wearing down more slowly. Less cell degradation means they don't need to divide as often, which means slower DNA degradation as well.
For most Deadbeats, these effects do not compound to a large change in lifespan, maybe 5-10 years more than average populations. But for individuals with extremely high chuubanite concentrations, the effect can be dramatic. A normal human muscle cell lives 10 to 16 years, but a Holy Ghost's muscle cells are densified, hardened chunks of force generation, and they might have a life span of nearly 50 years each.
So to answer the question, the injections have lengthened her lifespan by slowing down how quickly her cells age.
Also, yes, that is correct! Cuddling with a priestess every day might be able to expose you to significant amounts of Mori-type radiation. However, I think that would be a bit like holding uranium in your hands vs having uranium accumulate in your skeleton (which is what happens when you eat, drink and breathe on Moriji). The effective exposure would be much smaller. if the radiation source is outside of your body.
