A lot of technology sometimes break. We still use it. We routinely travel in steel boxes whizzing around at breakneck speeds where any serious mechanical malfunction or error leads to a quick death or very painful long term injury - and millions get hurt this way every year - but we take this risk because the rewards are higher. But with radiation somehow no reward is worth the risk - its radiation, how could you dare to rationally calculate risk/rewards if people can die!!!!11one1oen That's what I call "irrational".
