Why are Technetium and Promethium radioactive?

Hi,
I always wondered about this strange fact, considering the non-radioactive neighbour elements. Do you know why exactly these two are radioactive? Or is it just coincidence? Or unexplicable?
Thanks for any answers!

Hey, I'm not judging. I just like to shoot straight. I'm a man of science.
