PP: When "officials" on the so-called "radio" talk about radiation exposure in Japan. I understand that the levels people are being exposed to are small overall, however I don't think it is proper to state that there is no danger whatsoever. It smacks of the problem of classical toxicology in that the only dosage they are concerned about it is one that shows clinical symptoms. In other words, radiation sickness. What I would like to see are longitudinal studies showing that receiving a small "extra" dose of radiation does not manifest as sub-clinical symptoms (no obvious outward signs). I don't know that such studies exist for ethical reasons, and if they do then they would probably be studies commissioned after nuclear disasters such as this one. I'm not trying to be all OMG radiation death! I just wish the precautionary principle was something these people knew or cared about when they talk to the public. Am I being crazy?
