UPDATE BELOW!!!

2012 March 5th, South Korea, Chuncheon, Gangwon-do, a test of the rain that has been falling today.  I don't know if (and if yes then how much of this) any of this is due to naturally occurring radon raining out but the reading is certainly very high (peaks at 565+ CPM).

UPDATE:
It has been about 24 hours since I tested the collected sample.  In accord with advice given to me I retested it now and the reading was equal to the background (112CPM) thus confirming that the first (elevated) reading was indeed most likely caused by a radon220 rain out.  The area in which I live is mountainous and many houses and road surfaces are constructed of granite slabs or crushed gravel type material.  I believe that the overall higher readings in this area are mostly due to naturally occurring radon.  Without a lab analysis I am not able to confirm the presence or absence of any other radioactive substances.

I do not wish to cause any panic nor assign blame for the observed phenomenas where none is due.  As for living here, I still am going to err on the cautious side and relocate to a place about a hundred kilometers away where my readings revealed an average background radiation of about 20CPM.  Since, even though naturally occurring, radon has been linked to health issues it makes the avoidance of long-term exposure a potentially wise decision.
