ーーーーーーーーーーーーー it is sufficient to put 1 gram of charcoal in 1 litre of water over one night to get rid of iodine mostly 100%. (it does not absorb cesium at all unfortunately) it has been revealed scientifically also and was used in many similar cases in the past.
i went to visit mr.mrs. Satoh family who runs charcoal maker place. they lives positively in the rural area with laughter.
yes. it would be amazing if we live drinking water from taps daily.
the son had a radioactivity inspector when playing outside. all were putting masks on without hesitation. it was surreal but so real. we have to face the fact of the present situation. but with possible smiles. the family taught me the way of living. peace.
