Dr Chris Busby describes measurements made on an air conditing unit filter from inside an apartment in central Tokyo. This was sent by a lady in Tokyo who wanted to know if it was safe to live there. The filter only collected air from inside the apartment. It shows the presence of 130000 Bq/kg radio Caesium in the dust plus enriched Uranium and for the first time Lead-210/Polonium-210. The apartment was evacuated from the Tuesday after the catastrophe and the machine switched off; and the family returned 5 months later. This and much other information about the health effects and cover ups, including leaked data are to be found in Dr Busby's new book in Japanese: the Horror of Fukushima, published on 25th July by Kodansha in Tokyo.
