For your information, an average human body contains natural radioactive isotope of potassium - 40K. Every second there are approx.
3000 decays (Bq) of that isotope in your body. It means that every man is approx. 9 billions Bq "on release" per year. 40K emits 1460 keV gamma-ray (that easily goes out of your body) in about 10% of decays, the rest ends in beta-particle only, that stays inside. That's one of the problems of measuring release in Bq, which is not a good idea.
Anyway, your one trillion Bq is equivalent of mere 1000 people, if you measure radiation that goes outside of man body.
If Fukushima scares you, stay away from people. Don't hug them, kiss them, or - that's the most dangerous - sleep all night near them. Avoid crowded public places, gatherings, public transportation etc. Build a lead bunker. Wait! Radioactivity is already in your body!
For your information: in the link given by jkflying (http://isis-online.org/risk/tab7) you can easily find that the main component of the background radiation in Denver is radon (10.4 mSv/y). Radon, an alpha emitter (very short ranged radiation), is going into your lungs causing cells damage.
So there is no dramatic difference between the mysterious radioactive dust in Fukushima and Denver's radon. Moreover, I expect a lot of background radiation in Fukushima is in fact a gamma radiation, by far less harmful than radon in your lungs. Spent nuclear fuel emits mainly gamma and beta particles.
I'm amazed at how many anti-nuclear fans don't seem to know the basics.
I agree, this number is a non-sense. In fact it is not that easy to find a place on Earth, where the background radiation is as low as 1 mSv/y. Average US value is 3.1 mSv/y, Japan 1.4 mSv/y, there are exceptional places reaching over 100 mSv/y. To reach the 1 mSv/y mark, they are aiming at something that seems impossible to achieve.
They say it is 10-60 mSv/y next to a blown-up reactor. How much is it in a place where people actually live? 2, 5, 10? These numbers are perfectly acceptable (I live in a town with average dosage 5 mSv/y).
