    It's starting to look economically dire for so many in Japan besides the threat of radiation.

    Cost of the disaster look like to hit nearly $200 billion and with debt already at 5 trillion this will certainly bankrupt the government. People are already stocking up on Japanese food products and then abandon altogether because of the radiation threat.

    Now the stock market has wiped off 13% of the Nikkei and major manufacturers have stopped production.

    I think this makes sense.

    The method being used to measure ionizing radiation levels is useless. Radiation cannot be carried by the wind. The word radiation is not synonymous with radioactive material. Radioactive material can be carried, and this material can emit ionizing radiation. But the concentration of the radioactive material will be extremely low at a distance of 200km+ from the reactor, even in the worst case scenario.


    If the worst case scenario happens, the real worry is long term effects; Food/water sources being contaminated, causing long-term health problems, as the small amounts can build up over time. It WILL NOT be the case that people in Tokyo will suddenly be subjected to a level of ionizing radiation that can cause instant health issues. Even a nuclear warhead would not produce enough radioactive material to cause serious short-term health problems at a radius of 200km from the blast.
    So that reading is pretty much useless.

    You need to convert it to mrem,cCpm simply means counts/clicks per minute. How you make that conversion depends on the type of detector being used.

    The average total dose rate for the USA is 360 mrem a year. It has been estimated that your chance of dying from cancer increases 10% if you accumulate a total of 250,000 mrem. This would be over 3,000 mrem a year over 80 years, for example. This estimates presumably assume a linear risk factor between dose and the chance of getting cancer, and there are those who now dispute such assumptions, which means the risks from low levels of radiation may be overstated.
    Extremity (arm, leg, etc) Xray: 1 mrem
    Dental Xray: 1 mrem
    Chest Xray: 6 mrem
    Nuclear Medicine (thyroid scan): 14 mrem
    Neck/Skull Xray: 20 mrem
    Pelvis/Huip Xray: 65 mrem
    CAT Scan: 110 mrem
    Upper GI Xray: 245 mrem
    Barium Enema: 405 mrem

    Okay, the second one actually gives out a reading in μsv/hr. The description under the video says 0.16 is normal.

    But the International Atomic Energy Agency safety series 6 paragraph 205 states a maximum level of 0.6 µ Sv/hr as a safe level for persons working and 0.1 µ Sv/hr as a maximum level for the public.

    But like I said before, I'll take the readings with a grain of salt, it's the long term effects you have to worry about.
