I hope you don't sleep in the same bed as another adult, because you
will receive, and also give to them, a radiation dose from the ~5000 Bq
arising from the natural decay of Potassium 40 (K40) that is present in
your/their body. A gamma ray is emitted in about one out of every 10
disintegrations of K40, implying that about 500 gamma rays are produced
each second. These will be moving in all directions, and some will be
attenuated in the body. Gamma rays are really dangerous.

Well, the betas are probably more dangerous as they will mostly be
absorbed whereas the gammas will mostly pass straight through the
body without interacting.
