About a million people aged below 50 die of cancer annually, a study says, projecting another 21 percent rise by 2030.

    Tritium currently being dumped into the ocean in Japan but dont worry your bones can tell the difference between that and calcium no problem

      The fun thing is that your body can tell the difference between hydrogen isotopes and calcium.

        The deterministic effects are health effects that displayed symptoms due to the killing of tissue stem cells in those exposed to ionizing radiation at more than threshold doses for tissue reactions. The threshold dose for tissue reactions is defined as a dose to induce tissue injury at the level of 1% incidence [7]. Typical early effects resulting in symptoms appearing over several weeks after exposure to ionizing radiation, are acomia and permanent infertility, as well as skin lesions and hematopoietic disorders. Cataracts are a typical late effect with symptoms arising after a long latent period extending to decades after exposure to ionizing radiation. The threshold doses for acomia, permanent infertility and cataracts are 3, 2.5–6, and 0.5 Gy delivered to the whole body, respectively. When pregnant women are exposed to ionizing radiation, embryonic death and malformation are the deterministic effects, which are provoked in fetuses. The threshold doses for both are 0.1 Gy as whole body exposure dose (0.1 Sv, here, the sievert [Sv] is a unit of radiation dose used for radiation protection to assess the health risk on humans), which is the minimal threshold dose among the various deterministic effects. On the other hand, the stochastic effects are health effects displayed stochastically by accumulating DNA mutations in cells of the tissues exposed to ionizing radiation. Typical stochastic effects are solid cancer and leukemia. Therefore, health effects provoked by ionizing radiation at below 0.1 Gy as a whole body exposure dose (0.1 Sv) are only the stochastic effects. There is still no evidence, however, for the stochastic effects provoked by whole body exposure to ionizing radiation of less than 0.1 Gy (0.1 Sv).

      This comment comes across as horrible misinformed. If you want to make an argument for tritium being dangerous even at very low concentrations, make that argument. But tritium has nothing to do with calcium, and releasing low concentration tritium from nuclear power plants has been standard procedure for as long as we’ve had nuclear power plants. It’s not unique to Fukushima. France dumps more Tritium in a year than Fukushima will ever dump.

      You will have factors more dangerous levels of radiation if you spend much time in the sun.

      Interesting there are cities in the US that have background levels of natural radiation, levels higher than that allowed at nuclear plants. Check out places in Colorado. Yet they have cancer rates no higher than the national average. Some lower.

      The ocean alone has enough natural radiation that if we mined it out of the water, it could power the world for thousands of years. And actually there are ways to mine it for about 10c a kwh. That is economical but far higher than land based mining at about 2c per kwh thus no point in doing so.
