FACTS - Radiation Measurements in Japan

Enough of the media rubbish.... what is the truth??

List of measuring locations in Japan:
Environmental Radioavtivity Measurement Result

Table of measurements at these locations each hour:

So for Chiba (City nearest Narita Airport):
0.04 microsieverts per hour x 24 hours per day x 365 days per year = 350.4

which is lower than normal annual exposure in the table at:
Radiation Exposure in Daily Life

Not to say that the situation could not change without warning though I most sincerely hope that does not happen since a mate of mine is right now in Narita Tower.

But a little consideration of these figures indicates just how much the situation has been blown out of all proportion by the media.

Put it another way: The best of new airport x-ray machines will give you a 5 microsievert dose of radiation - equivalent to about 120 hours of exposure at Narita / Tokyo Airport at present.

Or your return flight from Narita to New York which will give you about 200 microsieverts of exposure is equivalent to around 5000 - YEP FIVE THOUSAND
HOURS of sitting out in the open air at Narita.

So if Aviation Professionals make RATIONAL judgements what basis is there for the current "FLEE" mentality? Or the FLEA mentality of a certain OZ politician?
Offered for the consideration of rational people.
