I am aware that a little over a year ago cesium escaped from the stricken Fukushima plant and then despoiled the farm land nearby. I think that one of the problems with radioactivity is that the “general public” do not know much about it and as you can not see it, hear it, smell it, taste it, or feel it with your normal senses the general public live in great terror of it.
I would like to point out that at very high levels (like the instant drop down dead level) people have reported that they have experienced odd sensations. I know one man who has had a “fatal” dose (a leukemia patient who got given a dose of radiation before a bone marrow transplant) who said that the radiation gave him a sore throat.
I would say that an understanding of something will dispel irrational fears and replace them with a set of rational fears. Having worked much of my adult life with and around radiation I am aware of what radiation can and can not do, for example a dose of radiation can not make me grow extra limbs but it can scorch your skin causing painful burns. Another thing which radiation can not do is to cause deterministic effects with low doses in humans (or other animals) nor can external exposure to alpha (or low energy beta) emitters cause serious damage to your innards but the alpha activity (Po-210) in cigarette smoke can cause dire damage to your lungs (Lung Cancer ? Nej Tac !).
I saw something interesting recently, it is all about cesium in meat.
J. Jandi, Josef Novosad, J. Francova and H. Prochazka in Veterinarni Medicina, 1989, 34(8), 485-490 wrote a paper about how to remove cesium from deer meat. They found that pickling meat removed much of the cesium radioactivity. A similar observation was made by R. Wahl and E. Kallee, Nature, 1986, 323, 208 where they found that a cesium contaminated roebuck deer meat could be decontaminated by soaking it in sodium chloride (common salt) solution. It is interesting to note that when the latter authors wrote up their work they commented on the taste of the meat.
