It's more comparable to
the background radiation dose in a single day.
But applying 3 times the annual
background radiation dose to any part of your body in a 2 - 3 second interval can't be good.
Not exact matches
Experts say the
dose from the backscatter is negligible when compared with naturally occurring
background radiation, but a linear model shows even such trivial amounts increase the number of cancer cases
Levels detected in a short duration pulse at the plant itself have reached as high as 8,217 microSieverts per hour, or eight times the
dose endured in a typical CT scan and four times the normal
dose of
background radiation in a year.
The response was proportional to
radiation dose, and in the most contaminated regions, the leaf loss was 40 percent less than in control regions in Ukraine with normal
background radiation levels.
It is based on the idea that any
dose of
radiation can be expressed as effective
dose equivalent in terms of the natural
background radiation we receive each year.
A typical nuclear medicine procedure may impart a
radiation dose to the patient comparable to about one to four years of natural
background radiation depending on the type of study.1 As with X-rays, the value of diagnostic imaging is great and the risks are negligible compared to the health benefits of having the procedure.
The distributions of annual external
doses estimated for each region overlap with each other, demonstrating that the personal external individual
doses in locations where residence is currently allowed in Fukushima Prefecture and in Belarus are well within the range of estimated annual
doses due to the
background radiation level of other regions / countries.
The additional exposures received by most Japanese people in the first year and subsequent years due to the radioactive releases from the accident are less than the
doses received from natural
background radiation (which is about 2.1 mSv per year).
Furthermore,
background radiation in the US is now dominated by human exposures, so any hypothetical minimum in the
dose response curve set by evolution has been passed for many people.
