An interesting article, including some radiation measurements and comparisons from cities around the world.

Typical amounts of radiation in Hong Kong exceed those in Tokyo even as workers struggle to contain a crippled nuclear plant in northern Japan, indicating concerns about spreading contamination may be overblown.

Natural radiation makes up about 85 percent of the global total, according to the World Nuclear Association. Manmade contributors include medicine and buildings, as well as the nuclear industry, which accounts for 1 percent of the total, the association says. Foodstuffs also contain radiation, and a 135- gram (4.8-ounce) bag of Brazil nuts has a dose of about 10 microsieverts, according to the U.K. agency.

Clearly, it's time to evacuate the planet.
