This video shows radiation levels on May 29th 2011, in Fukushima city (Japan) about 60-65 km from the Fukushima Daiichi nuclear reactors.
Measurements are made by a CRIIRAD scientist (Bruno. Chareyron, engineer in nuclear physics) during a meeting between CRIIRAD and Japanese citizens : M. Wataru Iwata (co-founder of Project 47 and CRMS) and persons in charge of the network "Fukushima Network for Saving Children from Radiation", including M. Nagate (ex-representative), Mrs Marumori (now Executive Director of CRMS) and Mrs Sato. CRIIRAD is sharing its experience of independent radiation monitoring with the Fukushima citizens.
In this video, CRIIRAD researcher is using a gamma radiation detector (DG5 scintillometer) to show the intensity of radiation rates, even inside the office at floor level. Radiation rates are given in counts per second (c/s). With this device, normal values should be about 50 to 150 c/s depending on natural radiation.
The powerful gamma radiations emitted by radioactive caesium deposited on the ground of the parking located in front of the building give a radiation rate about 10 times above normal values inside the building (at the centre of the office), and 15 times above near the window. This radiation will decrease only very slowly. After one year, the decrease should be about 23 % only.
