They also include less - visible sources, such as radiation and electromagnetic stressors from cell phones and towers.

Nutritional ketosis has received a lot of attention by cancer researchers in recent years, and many studies show it has great potential not just as a form of cancer prevention but also treatment — in combination with other treatments such as chemotherapy and radiation.16 Research is looking at whether non-toxic metabolic therapies and drug cocktails may be just as effective, with less toxicity.

Radiation exposure to your pet is also reduced as we use far less radiation for digital radiography.

In order to attempt to cure certain cancers, an intensive protocol will be ordered which usually requires outpatient radiation treatments for 16 to 20 days Palliative radiation therapy is a less intense protocol, and can be described as comfort care.

Fewer retakes are required, resulting in less radiation exposure for both the patient as well as the staff.

I personally doubt that any improvements that might have occurred subsequent to radiation were due to more than the distraction of the procedure or some undiagnosed, underlying cause (such as infection or cancer) that could have been treated less drastically.

Allowing for that falling on the oceans, and further decline due to angle of incidence as distance from equator increases, less the amount required by vegetation for photosynthesis, we are left with how much energy for conversion of solar radiation to heat / electricity / catalytic reaction to other fuels?

Will less ice and snow in the Arctic during winter increase, decrease or be about the same radiation loss as years with thick multiyear ice?

Thus the radiation heat balance, according to the IPCC, in the NH must be far less positive than in the SH (as example: a loss of 5 W / m2 TOA due to aerosols in the NH Indian Ocean).

What I meant was that Planck radiation increases with body or amb ient temperature, but higher temperature, per the Boltzmann distribution, makes it more probable that rotation, vibration, and / or electronic levels will be excited, and therefore less likely to emit relaxation energy, though as you point out this may not be exactly what happens physically — emission radiation is more flat than anything with increasing temperatures.

The gravity of the overall global temperature rise can not be overstated, climate engineering / solar radiation management is not a form of «mediation» as those in power would have us believe, geoengineering is a weapon of mass deception and war, nothing less.

After Mount Pinatubo erupted, while overall solar radiation was reduced by less than five percent, data showed a reduction of direct radiation by as much as 30 percent.

Now, when the energy received directly from the Sun at the surface of Venus is less than 10 % of what we receive on Earth, then there is less than 10 % coming back as back radiation — far less in fact.

The atmosphere as a whole is more energetic and there are therefore more photons bouncing around — more escape directly to space balancing more or less the incoming radiation.

Plus 5 % of the population have gene variants that mean their DNA repair is not as good as it could be and therefore they need a lot less radiation to cause a problem.

This is about the radiation from the Earth to space, which is prevented by the atmosphere's greenhouse gases, and as we pour more and more greenhouse gases into the atmosphere, less energy will be sent into space.

Hence as the upper troposphere contributes an increasingly greater share of the radiation to space with rising GHG's, it does so less effectively because it is colder than the lower troposphere.

If there's no radiation from the Sun, no heat capacity in the model planet, no mass big enough to effect pressure changes («real» ideal gases which don't have mass), nothing much is happening because there's no movement, (movement from the play of hot and cold volumes as hot gases rise and cold sink, becoming less dense and gaining density), but,
