Tepco said yesterday it detected 5 sieverts of radiation per hour in the No. 1 reactor building. On Aug. 1 in another area it recorded radiation of 10 sieverts per hour, enough to kill a person “within a few weeks” after a single exposure, according to the World Nuclear Association.
Radiation has impeded attempts to replace cooling systems to bring three melted reactors and four damaged spent fuel ponds under control after a tsunami on March 11 crippled the plant. The latest reading was taken on the second floor of the No. 1 reactor building and will stop workers entering the area.
“It’s probably the first of many more to come,” said Michael Friedlander, who spent 13 years operating nuclear power plants in the U.S., including the Crystal River Station in Florida. “Although I am not surprised, it concerns me greatly; the issue is the worker safety.”
NOTE: This 10 sievert reading MAXED the Geiger counter, that means it is likely higher. Now the question is how large an area has these lethal exposures.
