Both of these mubers may be off. The things we're recommending will throw a reasonable ascumt of light on this because out of cur pilot program aswuming it is done one will measure the soil radicactivity, the plant radioactivity and the radloactivity in bumen tones. Among other things, we are also going to measure, if it can be done, the strontium content and the caloium content and so one should in a few months be able to move _@ut of the range of fancy into the range of fact. Why do you have to get into the radioactivity part of it at all. Why not carry out a progres where you measure the strontius in the soil and say in the water and in bone and re-do these and get good values? How about msasure sewage?
