Sentences with phrase «radiation levels near»

And even when there was water, he notes, «the hardiest cells we know of could not possibly survive the cosmic radiation levels near the surface.»

Workers spray, allow the radioactive steam to dissipate and then spray again — radiation levels near reactor No. 3 are the highest at the plant, roughly 400 milliSieverts per hour.

One of the big advantages of the approach that this paper uses is that, to decide on a strategy, evacuation officials need to consider only the radiation levels near shelters and along evacuation routes — the overall pattern of the radioactive death - cloud does not factor into the models.

Not exact matches

This amount of radiation is absolutely deadly to any one exposed for any length of time — You are dead within I hour with this level of exposure, This latest development has scuttled TEPCO's plans to decommission what's left of that exploded reactor because no one can be near enough to it to disassemble the wreckage.

A team from Fukushima University recently mapped radiation levels at 370 spots in the prefecture and, using weather balloons, confirmed that atmospheric radiation levels have dropped to near background levels.

Many smart phones, for example, put out higher levels of radiation, and the use of wired headsets can decrease the amount of energy emanated near the head.

As part of the Building a Better Explainer project at N.Y.U.'s Studio 20, we decided to create a visual explainer of radiation levels, inspired by some recent presentations over at XKCD and Information is Beautiful.Both compare radiation doses from everyday activities (like eating a banana or flying across the country) to doses near the Fukushima plant, as well as other disasters like Chernobyl.

The Army's brochure for visitors assures us that radiation levels in the area are «very low,» ranging from 0.05 millirem near the parking lot to as much as 10 times that amount in the ground zero area.

Instead of measuring seismic activity near volcanoes the device monitors levels of neutron radiation around them.

Moreover, in the extreme cold of the upper troposphere, ozone's radiation - trapping properties are thirty times greater than at ground level, says Colin Johnson at AEA Technology near Oxford.

FULL - BLOWN FALLOUT Remnant radiation levels from nuclear testing near Bikini Atoll in the Pacific Ocean, as seen in this explosion in 1946, are far higher than previously predicted, new research shows.

What's more, oncologists can program the IMRT machine to deliver these radiation beams with varying levels of intensity, so that the higher toxicity beams are not aimed near healthy tissue.

The effect where, adding a «new» absorption band and increasing the absorption, there may initially be warming of the colder layers, etc, followed by a stage of upper level or near - TOA cooling — this includes the warming from absorption from increased radiation from the surface + troposphere — which will be greater when more of the spectrum, especially near wavelengths where the emitted spectral flux change is greatest, has a greater amount of absorption.

The net result is an upward transfer of infrared radiation from warmer levels near the Earth's surface to colder levels at higher altitudes.

It determines how much of the radiation delivered to land goes into warming the near - surface atmosphere compared with how much is released as latent heat fuelling precipitation at higher levels.

* the water vapour content of upper layer of the air (in blue figure 6 - D) will change by about 12 % / K near the tropopause and is reduced by the enhanced cooling of the 250 mbar layer; hence the water vapour radiation will the be from a «lower and warmer» level, with a very significant spectral leverage of a factor of ten (400 cm - 1 for the water vapour w.r.t to 40 cm - 1 for the CO2).

[44] a reduction of 1/7 of the water vapour content of the air near 300 mbar pushes down by a factor 1 / (1-1/7) 4.7 = 1.03 the P80 % level and the P80 % temperature increases by a factor 1.030.19 = 1.006 that is by about 1.5 K for the radiation temperature over the far infrared spectral range

«This H2O negative - feedback effect on CO2 is ignored in models that assume that warm moist air does not rise and form sunlight - reflecting clouds, but remains as humid air near sea level, absorbing infrared radiation from the sun, and approximately doubling the temperature rises predicted from atmospheric CO2 increases.

The effective average location of outgoing radiation is about 5 km, so the lapse rate times 5 km = -33 C. Note that the higher ground and thus air temperature near the ground then cause the higher radiation levels.

Dr. David Evans (personal communication, 2007) has calculated that the characteristic - emission - level value of κ should be diminished by ~ 10 % to allow for the non-uniform latitudinal distribution of incoming solar radiation, giving a value near - identical to that in Eqn.

There is no consistent evidence of human health effects from exposure to extremely low - frequency electromagnetic radiation at much higher levels than is present near wind farms.

And remember, we are talking about an additional radiation exposure in the realm of 0.0002 mSv for those living near a nuclear power plant, versus a background level of 2 to 4 mSv (depending on where you live) due to everything from cosmic rays to ground - derived radon emission to eating bananas (this last one gives you more radiation than the NPP).
