Japanese authorities said they had measured radiation dose rates of up to 400 millisieverts-per-hour, IAEA reported.

Overall, Mars' atmosphere reduces the radiation dose compared to what we saw during the flight to Mars.

In normal circumstances, a passenger might receive a radiation dose of 0.1 millisieverts on such a journey, she explained.
We expect that the HC1 will provide us with measurable gains in productivity and efficiencies that will reduce radiation dose and operating costs.
If an astronaut had been on the Moon at the time, they might have received a 400 rem (Roentgen Equivalent Man) radiation dose.

The radiation dose from an individual dental X-ray, Dr Claus points out, has gone down by about half over the past 30 years or so.

Finally, sequential scans take a series of pictures of the heart at the same exact point in the cardiac cycle, which also reduces radiation dose.
More than 70 percent of the centers in the study were using electrocardiographically controlled tube current modulation (ECTCM), which is currently the best-known strategy for reducing radiation dose.
The technique, called Image Guided Intensity Modulated Radiotherapy Treatment uses imaging provided by a CT scan to target the tumour before a powerful but precisely shaped radiation dose is administered.
Dr. GERBER: It's approximately four times the natural radiation dose that we all receive annually in the Unites States, as a result from background radiation due to radon and other materials.
Professor Joe Sedat says that even though the radiation dose may be low, it may be intense where it hits certain parts of the body like the cornea, the testicles or the skin.

Recently the government said it needed to clear about 2, 419 square kilometres of contaminated soil an area larger than greater Tokyo that received an annual radiation dose of at least five millisieverts, or over 0.5 microsieverts an hour.

"Specifically, to reach annual radiation dose limits, a passenger would have to receive more than approximately 17, 000 screenings in a 12-month period, which is equivalent to approximately 47 screenings per day, 365 days per year, " the inspector general's office concluded in an executive summary.
Dr. ANDREW EINSTEIN (Cardiologist, Columbia University): Using beta-blockers or other medications to lower patient's heart rate, which in many cases will chip the radiation dose down by minimizing the number of images which are taken, and matching the technical parameters such that the patient doesn't receive too many x-rays.
The developing fetus and infant has demonstrated a predisposition to cancer from various types of low-dose radiation exposure within a decade.

It will also provide a stereotactic radiosurgery service (SRS) which involves the precise delivery of a single fraction of high-dose radiation, usually within the skull.
They found that although the fetus did absorb radiation, the dose was 40% less than that calculated by a more rudimentary software tool that is currently in use.
Some experts said it was surprising that any increase in cancer was even predicted and believe that the low-dose radiation people in Fukushima received hasn't been proven to raise the chances of cancer.
Because fat can disperse the waves, overweight people usually need a higher dose of radiation in medical procedures.
And the tissues surrounding the organ inevitably receive a large dose of radiation.
After five years, 109 of the women who had received the extra dose of radiation had seen their tumours return.
"Many doctors expected that using a higher dose of radiation would mean better outcomes for patients, so this was a surprising result, " Swain said.
Unfortunately, those four filters mean you also have to take four separate images to get one clear image, giving the patient quite the extra dose of radiation.
Prof Vallis said "it is attracted to DNA damage", where it then delivers a dose of radiation, causing more damage and attracting even more antibodies - it is a "self-amplifying system".
The federal government has insisted ever since the TSA decided to install 300 full-body scanners, or strip searchers as critics call them, that getting a small dose of radiation is safe.
FORBES: Would You Rather Risk Getting Cancer Or Just Get Your Privates Patted?
Louis, found that a 25% stronger dose of radiation used to treat patients with one type of lung cancer were more dangerous for the patients -- and less effective in treating the disease.
Conventional CT scans are used to work out the shape of the place where a dose of radiation needs to be concentrated in order to attack a tumour without damaging nearby healthy tissue.
Even subsistence fishermen, who eat far more fish than the typical American, would receive a dose of radiation from the cesium isotopes released in the meltdown equivalent to a single dental X-ray, Fisher and his colleagues reported.
