The thing is we are going to need to embrace nuclear power to even attempt at satisfying future energy requirements. There isn't going to be any kind of 'China syndrome' in Japan and that disaster isn't about to kill the worlds' oceans off. The energy companies are adept at peddling nonsense but so too are organisations like Greenpeace who prefer sensationalism over proper science. It is our responsibility to filter fact from fiction — whether that is what the corporations are telling us or environmental groups. Both peddle crap but it is down to us to discern the truths.

People said Chernobyl would end the world and leave swathes of uninhabitable land and guess what, they were wrong. Nature reclaimed things quite quickly and shortly after residents were moving back in to their homes.
wrong, there are areas near the site no one goes, many, many people with effects from the meltdown and subsequent hydrogen explosion, but this is much bigger...3 uncontrolled cores in the water table RIGHT on the pacific ocean, anyone can say what they wish, go ahead, but this is just the start of this story and it will show more and more signs as days go forward......

Anyway, if you insist on buying a Geiger counter, here are some tips:
When using a Geiger counter like this, seeing spikes of two or three times normal background is not unusual, so don’t panic if it does this. Background radiation varies considerably from daylight to night time, so expect this. If you move the meter around, expect variation. I don’t know about this particular meter, but just the motion of moving the meter will swing the needle on some meters (geotropism) and give you a false reading. The detector should be facing up if you are measuring background airborne contamination such as we may get from Japan. However, areas with relatively high radon levels may cause deposition of radon daughter products on the detector causing elevated counts over time, so I put a piece of tissue over the detector (I lose alpha counts doing this). Be careful where you put the meter, you may be in a naturally “hot” area. Be careful what you bring around the meter, there are lots of things in our personal worlds that can cause elevated counts.
You can distinguish alpha, beta or gamma emissions by doing the following:
1) put a piece of tissue paper over the detector. If the counts drop dramatically you are measuring an alpha emitter. Side window detectors, such as seen on the old Civil Defense meters, won’t detect alpha particles. Even pancake detectors such as used by the Inspector above have a very low efficiency for alpha particle detection. So if you see a dramatic drop when you put tissue over the detector, you have a serious radiation problem.
2) Put a 3/8 inch piece of plastic or wood over the detector. If the counts drop dramatically you are measuring a beta emitter such I-131 (also a gamma emitter so it may be a little confusing). The pancake probe on the Inspector is typically about 30% efficient.
3) If the counts don’t drop much after doing the above, you are measuring a gamma emitter such as Cs-137. Most of your normal background counts are X-ray/gamma emissions from the sun and natural radioactive materials that are all around us.
If you spill something on the detector, don’t try to clean it yourself – guaranteed you will ruin the detector. Have the manufacturer replace it. If your Geiger counter has a cable for the detector, it is not unusual to see the cable go bad and it will peg your meter. Don’t stick your tongue to an attached cable – there is about 500-1000 volts running through it. The window on a pancake or end window detector is fragile – I had a stalk of stiff grass break one ( I won’t say how many I’ve broken).
How do you know your detector is calibrated properly? You won’t. However, if you can get hold of a source of radiation such as old, orange FiestaWare, you can see if there is any change in your detector over time. It is critical, if you do this trick, to make sure you maintain the same geometry each time, i.e. the exact same distance from meter to source and exact same location of source relative to detector. With a uranium source such as found in FiestaWare, you should see very, very little decrease in counts over a year or more.
The above are just a few things you need to understand when using a Geiger counter. If you do not get decent training on how to properly use a meter like this, I personally think you are wasting your money, but it is your money and I like most of the companies that make radiation detectors so be my guest. Proper training also includes a course on how radioactive atoms and radiation interact with matter and, by extension, the detector.
Ive come to the conclusion that ignorance is bliss as far as Fuku, there is literally nothing we can do. Banks, governments, GMO foods we still have time but with Fuku we are literally helpless. Im hoping this whole thing is kinda like Ison and Nibiru and no one outside of sites like this pay any attention and it goes away, sadly I dont think this will be the case. Fuku is a big Fuk u to the whole world from the people who brought us "safe and clean" energy. I am now choosing to firmly and deeply bury my head in the sand on this issue like the good sheeple I am

It isn't going to happen and you are just supporting more kook environmental nonsense.

I've been to the half moon bay beach you show (whales and sea lions like to sun there). I don't see the similarity. The half moon bay cliff drop is a much steeper trail. He would have been doing zig zags to get down. Maybe I'm misunderstanding because if he is filming from two different beaches and splicing them together that's weird - would definitely see a loss of credibility. However - I don't see the beaches being the same one.
Maybe this isn't from Fukushima at all. If someone is noticing those readings I think instead of just posting on you tube they need to contact someone to tell them/ask. What is the safe limit? None has stated above 100 is safe and the site with the radiation map says it isn't. Northern California is usually between 20-40. It could be something simple that is naturally occurring but it would be nice to alert someone incase it isn't.
Fact is: radioactivity frightens people, almost always disproportionately to the actual threat: gouvernment must recognise this and provide sound, science based knowledge (and wisdom?) on human and environmental risks.
