Links to radiation level information in Japan

Here are some links to check for current radiation levels in Japan (In Japanese, but you can use google translator to get a quick rough translation if need be):

The number of units [nGr / h] and in this "gray per hour nano" and reads.

n (nano) size of the numbers →. m (mm) μ → (μ) → n (nano), and then will become the 1000 / 1. A micro-nano-1000, Micro 1000 is one millimeter.

Gr (Gray) is a unit of intensity of radiation →. In the report "Sv (sievert)" We have units that are commonly used, in this case largely "1Gr = 1Sv"

/ H (per hour) per hour 1 →, which means. Value that is displayed there is to say that the total value per hour. Get away in 10 minutes if the intensity of the radiation exposure is <6 / 1.

If A Value of 30 [nGr / h] is displayed , to stay there for one hour, will result in exposer to a radiation level of 30 NanoSv roughly.
