Brief radiation spike on Kauai

[snip]

SUBHEAD: We had a brief but significant spike in radiation today that was over 30 times normal background level.

In early November I bought a Radex RD1212 radiation monitor from Amazon. The Radex is Russian made with an English menu. It's simple ans seems to work fine. One feature of the unit is that it keeps a record of the time and strength of radiation it senses.

I used it daily at first to get an idea of what was normal here on Kauai. The unit measures in micro-sieiverts per hour. That's a millionths of a sievert. As a reference;
  • A person can safely be exposed to 3,650 micro-sieiverts in a year or .4 micro-sieiverts/hour. 
  • A radiation worker in the US is limited to a dose of 50,000 micro-sieiverts in a year. 
  • A person who absorbs 100,000 micro-sieiverts in a year is considered to have a clear increased cancer risk. 
  • A person absorbing 2,000,000 micro-sieiverts will suffer severe radiation poisoning that could lead to death.
