This scans an area of wall and picks up varying levels of radiation emanating from it.

And simple screening — with Geiger counters and the like — of soil, food and seafood can pick up radiation at low levels (so low, in fact, that the lower - end readings indicate contamination that not likely to be harmful).

On the moon, they will have to move quickly — the radiation will hit within an hour of their learning of it, and doses could build up to an unacceptable level in three to four hours.

With higher CO2 levels and temperatures, low - level cloud shrank by up to 10 per cent, letting in even more solar radiation (Journal of Climate, vol 23, p 5844).

In the malignant tissue, they found up to 1500 genes with mutations — a level higher than has been found for either lung cancer in smokers or skin cancer in patients with heavy exposure to ultraviolet radiation.

A new computer simulation suggests that the water vapour and sea salt thrown up by the impact could damage the Earth's protective ozone layer, leading to record levels of ultraviolet radiation that could threaten human civilisation.

These fast - moving bands of winds are found in the upper levels of the atmosphere and are created due to Earth's rotation, and its air being warmed up by solar radiation.

Exposure to radiation (although considered minute), cramped spaces, and potential infections (from other passengers on the plane), and the stress of changing time zones (forcing your circadian hormone levels to adjust) can all add up to quite a stress, especially for frequent fliers.

Rooibos tea has up to 50 % more polyphenols and antioxidants than Green Tea (1) and can be a great alternative with recent concerns about radiation levels in green tea.

Miami seems to fall in a nice zone where you still get the heat and humidity water and fat loss benefits of hot weather, but they are turned up a notch over, say, NY, with the almost tropical level UV radiation on top of it.

I got mixed up and made it sound as if the increase in downward radiation subtracted from the effect of decreased upward radiation, but the opposite is of course true — both effects contribute to a decrease in the net upward radiation at the tropopause level.

A simple (dirty — uncontrolled) experiment Central heating radiator Thermocouple (0.5 mm bead — fast response) inside cardboard tube 1cmx1cm (to isolate from radiation) Height at level of radiator top Still Air 50 cm 23.8 deg C 10 cm 23.6 deg C (convection currents drawing cool floor level air up through tube?

Rather than break up low level clouds, skeptics see the water vapor adding to the low, thick clouds (such as stratocumulus) which primarily reflect incoming solar radiation back into space.

The time scales involved remain miniscule on the level of an individual molecule BUT on a planetary scale they become highly significant and build up to a measurable delay between arrival of solar radiant energy and its release to space as outgoing radiation.

Note: At least one of the YouTube posters (Shazzy Mazzy of The News Insight) and Victoria Woollaston, the reporter who covered the drone tapes from the Daily Mail Online, appear skeptical about radiation dangers to life on earth: «many of these areas are said to be covered in radioactive soil,» «reports claim the soil and water in the region still contains high levels of radiation that makes the clean - up effort difficult.»

I can point to experimental evidence showing the rapid build - up of CO2 in a car with a sleeping infant and windows closed leading to rapid temperature increase and death, but we are not living in closed cars, and the atmosphere's CO2 at even 760 ppmv falls well short of the dangerous levels in that experiment (which of course said nothing about radiation).

While actual scientists are trying to piece together every little part of an otherwise almost un-piecable long term chaotic and variable system in response now to a massive increase in net lower atmospheric energy absorption and re radiation, Curry is busy — much like most of the comments on this site most of the time — trying to come up with or re-post every possible argument under the sun to all but argue against the basic concept that radically altering the atmosphere on a multi million year basis is going to affect the net energy balance of earth, which over time is going to translate into a very different climate (and ocean level) than the one we've comfortably come to rely on.

And, what ends up mattering there is, essentially, what level the radiation that does escape into space (as opposed to being re-absorbed) is emitted from.

The model also does not take into account dust and water in the form of clouds which both hold great quantities of CO2 and which takes it directly and quickly into the carbon life cycle at ground level and uses it up and none of this directly absorbed solar radiation is taken into account in the model.

The only way CO2 could absorb any more IR than it is already absorbing is if 1) the surface started re-emitting more IR, which could only happen if more sunlight reached the surface, or 2) atmospheric water vapor levels dropped, freeing up more IR to be absorbed by CO2, in which case, warming would not occur, because that radiation was already being absorbed by the water vapor that disappeared.

The important thing is that the radiation at the lower levels has to make its way up through higher levels of the atmosphere before it is able to escape into space.

A bit of radiation does you good, certainly no har, up to 400 tims theevcuation evels that we can prove epidemiologically, but irrational fear and old hypothese that are just wrong keeps disproven beliefs as the basis for regulation and officials in hazmat suits waving meters where in radiation levels people all around the world live out normal lives in.
