Ask HN: Is there radiation fallout risk in California?
What would be the risk of unhealthy radiation fallout in California? Could the radiation clouds move over the Pacific?
Also these geiger counters, is it something civilians could buy and use? http://www.theaustralian.com.au/radiation-fears-sweep-the-re... Has an article on it. Basically you shouldn't worry, people were testing a whole bunch of atomic weapons during the cold war and everyone turned out alright. I am not sure an atomic bomb is a good comparison, I have heard nuclear reactors possess many multiples of radioactive material than a bomb.
