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.
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.
Marta Schulman, chair of the American College of Radiology Pediatric Imaging Commission, said the study adds to the impetus that patients should be scanned only when necessary and with the lowest dose of radiation possible.
But according to follow-up studies reported by the Nuclear Regulatory Commission (NRC), the resulting average dose of radiation that about 2 million people in the TMI area received amounted to 1 millirem, six times less than exposure to a single standard chest x-ray.
FORBES: Media Hype Over Nuclear Energy Increases Anxiety And Confusion
People living here in Palo Alto, Mountain View and the rest of Silicon Valley have been in a shopping frenzy, snapping up potassium iodide pills, dried foods, emergency kits and various other supplies out of concern that Northern California could receive a dose of radiation from the nuclear mess still unfolding in Japan.
FORBES: Radiation No Threat To Silicon Valley, Santa Clara County Says
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.
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.
ENGADGET: Curiosity rover finds radiation levels on Mars are safe for humans
In normal circumstances, a passenger might receive a radiation dose of 0.1 millisieverts on such a journey, she explained.
The backscatter machine "delivers an extremely low dose of ionizing radiation" with levels "below the acceptable limits, " the report stated.
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.
ECONOMIST: Confirmation that dental X-rays can be bad for you
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.
The BMA has been campaigning against sunbed use since 2003, arguing that just one session a month doubled the average individual's annual dose of UV radiation.
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.
