The radiation level in the containment vessel of reactor two has reached as high as 530 sieverts per hour, Tokyo Electric Power Co, or Tepco as it’s known, said last week.
Are levels rising?
Azby Brown reporting on Safecast’s website, February 4th:
No, radiation levels at Fukushima Daiichi are not rising
“It must be stressed that radiation in this area has not been measured before, and it was expected to be extremely high. While 530 Sv/hr is the highest measured so far at Fukushima Daiichi, it does not mean that levels there are rising, but that a previously unmeasurable high-radiation area has finally been measured. Similar remote investigations are being planned for Daiichi Units 1 and 3. We should not be surprised if even higher radiation levels are found there, but only actual measurements will tell.” (see more at Safecast)
Feb. 8, Denver Post: Could the radiation level be even higher? Possibly. The 530 sievert reading was recorded some distance from the melted fuel, so in reality it could be 10 times higher than recorded, said Hideyuki Ban, co-director of Citizens’ Nuclear Information Center.
