Has anyone considered how absurd it is to be afraid of this minuscule amount of radiation when patients with hyperthyroidism (Graves Disease) are routinely receiving many thousands times this amount as a routine treatment without fear?
An acute dose is a relatively large amount of radiation received in a very short time period.
Critics of cardiac CT angiography question whether its benefits warrant its current widespread use and the amount of radiation exposure.
Ouchi is believed to have absorbed about twice the amount of radiation that is usually considered fatal, though he may survive.
The amount of radiation likely won't change unless there's a rocket engine developed that can speed up the interplanetary ride, researchers said.
Certainly they do affect the amount of radiation coming from the sun.
If the amount of radiation from the reactors went up 100-fold, to 10, 000 microsieverts, it would still be a very low level, Brenner says.
Many factors can derail a phone from being certified, including the amount of radiation that it emits or how hot the battery can get.
But the UK study suggested that instead of offering protection, some hands-free kits acted as aerials and tripled the amount of radiation reaching the brain.
In a related editorial, cardiologist Andrew Einstein, from Columbia University, says there are methods labs could take to reduce the amount of radiation in these scans.
The TSA says the scanners are safe, exposing people to about the same amount of radiation they would get by flying for about two minutes at altitude.
But it forgot to mention that at today's cruising altitudes passengers are exposed to a considerable amount of radiation, especially on transatlantic flights close to the pole.
The second Chi-Med drug in trials, a radiosensitizer for head and neck cancer, helps make tumor cells more receptive to radiation by increasing the amount of oxygen in the cells.
Previously, the commission held that the amount of radiation released from FDI warranted only a level 5 designation on the International Nuclear Event Scale (which runs from 1 to 7).

Even so, only one year ago, progressive San Francisco Mayor Gavin Newsome proposed an ordinance that would have required that all retailers inform consumers about the amount of radiation that cell phones emit.
But the Milankovitch cycles barely affect the overall annual amount of solar radiation hitting the Earth!
FORBES: An 'Eccentric' Earth Offers More Clues to Climate Change
Changes in the amount of ultraviolet radiation from the Sun affect the ozone layer.
In addition to its weather-watching mission and collection of climate records, MSG-3 has a radiation sensor to measures the amount of solar and infrared energy that is reflected back into space, to better understand climate processes.
Other techniques aim to enhance marine cloud reflectivity by introducing sea salt aerosols in low clouds, mimic the effects of volcanic eruptions by injecting sulphate aerosols into the lower stratosphere, or place shields or deflectors in space to reduce the amount of incoming solar radiation.
The specific symptoms, the treatments available and the prospects for recovery vary from one person to another and are generally dependent on the amount and type of radioactivity, the radiation energy, the area of the body exposed, and the age and general health of the individual.
However, because it emits very low energy radiation and leaves the body relatively quickly, for a given amount of activity ingested, tritium is one of the least dangerous radionuclides.

The number of antioprotons exceeds, by several orders of magnitude, the amount of antiprotons that would be expected outside of the radiation belts.
The amount is extremely small and less than 1% of all other natural sources of radiation.
Such accidents do not usually spew out large amount of contaminated particles, as happened at Chernobyl, but they do give off intensive radiation.
Furthermore, the radiation that has already been released in and around the plant could make TEPCO liable for an unknown amount of damages incurred by local residences, businesses, and farms in the area.
