The doses from exposure to other radioactive isotopes, such as Caesium, with a physical half-life of 30 years and a biological half-life of 70 days, have been much lower — in the majority of cases equivalent to that of a single CT scan around 10 mSv.
There is still much we can learn about the nuclear disaster in Fukushima. Rather than strict guidelines, there are many lifestyle choices available to those who remain in Fukushima. Depending on the dose of radiation this ranges from skin rashes, vomiting and diarrhoea, to coma and death.
In general, where biological half-life is greater than physical half-life, the dose of radiation to a given tissue will be higher, and therefore the health effects are likely to be greater. How have researchers learned about cancer risks from nuclear power plant accidents?
It is therefore unsurprising that medical professionals do not yet agree on how to advise older patients about continuing or abandoning old ways of living, and differing perceptions of the importance of radiation risk magnify the difficulty of this task. High enough doses also damage brain cells and such doses are invariably fatal.
Children and adolescents are more sensitive to the cancer-causing effects of ionizing radiation than adults because their bodies are still growing and developing.
