The local background radiation average for the month of October was elevated at 19% above the four year recorded average. It was also a very volatile month, with dynamic swings in local background radiation levels. These dynamic swings in background levels were tied to wind direction. Northerly wind direction consistently increased local background levels of radiation.
At the beginning of the year, we had lots of short duration spikes in radiation, that were detected up the eastern sea board of Australia and in New Zealand by independent testers. Now we are seeing broader increases over longer longer periods of time.
After doing a lot of rain swab scintillator tests, what was detected were increased radioactive Radon gas levels. Here is a link to information on Radon gas.

The local rain washout test chart below, shows the Radon daughter isotopes of Lead, Pb-210 and Pb-214, plus Bismuth Bi-214. All that was left after leaving the test sample for a week, was the long life Radon daughter Pb-210.
There are a number of theories that have been put forward for the increasing Radon levels.
50 times more Uranium than normal was detected in air over Hawaii on the 21.03.2011.
Medium : Air-filter
Location : Hawaii
Nuclide : Uranium-238
Date : 12/31/2010
– Result : 4 aCi/m3
Date : 3/21/2011
– Result : 215 aCi/m3
All this extra Uranium that has been aerosolized into the air from the Fukushima Nuclear Disaster into the Northern Hemisphere atmosphere, is constantly releasing extra Radon gas. This would explain the increase in radioactive Radon gas coming across the equatorial boundary from the Northern hemisphere.
Also, there are constant steam releases from the underground super heated melted Nuclear reactor cores, hitting ground water. This releases a lot of extra Radon that is in the cores and soil at Fukushima. Watch this video from the 30.10.2012 to see a live shot of ground venting at the Fukushima site, from the underground Nuclear reactor cores. This is a common occurrence there.

Radon has a half life of 3.82 days so it is around for at lease 38 days. You multiply the half life of an isotope by 10 to get the effective life of it in the environment. If a sufficiently large enough extra amount of Radon is continually being produced in the Northern Hemisphere atmosphere, there is plenty of time for it to get here, and be detected, if the weather conditions are favourable.
Radon Theory Two
Increasing Radon levels have nothing to do with Fukushima, but by increased global temperatures, or seismic activity in the Northern Hemisphere.
Any increase in background radiation levels, or Radon levels presents an increased health risk. Radon is the second biggest cause of lung cancer, after smoking.
