Such accidents do not usually spew out large amount of contaminated particles, as happened at Chernobyl, but they do give off intensive radiation.
However, U.S. officials are calling for U.S. citizens to leave Japan and the recent water cannon work has been called off due to radiation levels.
Hollis-Eden's drug, an immune system booster, appears to help the bone marrow fend off toxic effects of radiation and could be used by troops going into battle to protect against the effects of dirty bombs.
Depleted uranium gives off relatively low levels of radiation, but can be dangerous if ingested, inhaled as dust or if it enters the body through cuts or wounds.
The material gives off relatively low levels of radiation, but can be dangerous if ingested, inhaled in dust or if it enters the body through cuts or wounds.
Further, study of the captured space rock could teach researchers how to efficiently extract water from asteroids a resource that could be an off-Earth source of radiation shielding and rocket fuel for journeying spacecraft.
MSN: NASA might lasso an asteroid and drag it to orbit near moon
The angle of the radiation a particle gives off reveals its velocity.
Shares of Radiation Therapy Services cooled off in 2006 with Medicare vowing to cut reimbursements for IMRT procedures by 27% over four years.
Even something too small to emit visible light will probably give off radio waves and infra-red radiation (Jupiter does).
She has a doctor's order for the screening but has put it off, noting conflicting reports and concerns about radiation exposure.
Gas clouds in the middle of the galaxy are, everyone agrees, partly ionised: radiation flying through has battered electrons off some of the atoms in the gas.
An explosion in the middle of the night at the Chernobyl nuclear power plant in Ukraine tore off the plant's roof and sent radiation over much of Europe.
Ms. SUZANNE THOMASSEN-KRAUSS (Textile Curator, Smithsonian Institution's Museum of American History): When you look at a lit object, what you're getting is only the light radiation that's reflecting back off the object.
X-rays and gamma rays that Eros gives off in response to bombardment by solar and cosmic radiation.
The earthquake launched a tsunami, which killed thousands, and knocked out the nuclear power plant at the Fukushima Dai-ichi nuclear power plant, about 140 miles northeast of Tokyo, setting off a series of explosions, fires and large radiation leaks at the facility.
But Dr Mousseau suggests a more likely explanation is that evolution has already been at work near Chernobyl, killing off individual birds that cannot cope with the background radiation and allowing the genes of those that have some tolerance to be passed on.
She also asked whether the AWE off-site contingency arrangements, aimed at protecting the public from a radiation emergency, were put into operation.
But then, our radiation supervisor switched on the detector in the compartment and it went off the scale.
The levels were tested when the phone was in use (transmitting radiation) against the head and when against the head but in the off position.
While the plant owners are responsible for managing efforts to limit the fallout of radiation leaks on site, it is FEMA that is in charge of off-site activities.
Once the cancerous area is precisely targeted, only the intensity of the laser radiation needs to be turned up in order to irradiate, or burn off, the tumor.
ENGADGET: Researchers develop femtosecond laser that can diagnose, blast cancerous tumors
The telescope gathers and focuses electromagnetic radiation (usually, but not always, visible light) to make far-off objects seem brighter and closer.
Mobile phones must be switched off on site, and the microwave in the common room resides in a Faraday cage to stop radiation escaping.
This radiation can be detected although Dyson spheres remain difficult to distinguish from natural astronomical objects that give off similar signatures.
ECONOMIST: Is it time for a new approach to finding extraterrestrials?
But the slow decay in radiation intensity from a tabletop pulsar would make possible extremely long-range transmitters, giving far-off space probes an energy-efficient way to beam information back to earth.
