Sentences with phrase «radioactive decay energy»

Because the energy source is symmetrically distributed throughout the shell wall, at some point the external surface of the shell will reach a temperature such that the rate of energy radiated outward by this surface will be equal to the rate at which radioactive decay energy is generated internal to the shell wall.

In the 1920s, for instance, radioactive beta decay perplexed many physicists because it seemed not to obey the law of conservation of energy.

This explains why it took researchers nearly 30 years to catch a first glimpse of neutrinos, although their existence had been first postulated in 1930 to explain an apparent violation of the conservation of energy in the radioactive decay of unstable atomic nuclei known as beta decay.

What makes the pp reaction hard is that the neutrinos have very low energy that is about the same as the energy of various radioactive decays that happen on Earth, making it easy for an earthbound detector to confuse a decay with a neutrino event.

decay (for radioactive materials) The process whereby a radioactive isotope or particle sheds energy.

While the tremendous increase in luminosity is given by energy liberated by the explosion, its gradually fading light is fueled by radioactive cobalt decaying into iron.

I've heard that one can speed up radioactive decay slightly by compressing the radioactive material, but the best speed - up I've heard of is only one percent, and the compression would probably consume a lot of energy.

On the Earth, the internal energy comes from radioactive decay and the ongoing differentiation of the Earth.

The energy source for geothermal electricity generation is the tremendous heat flowing from the Earth's core and mantle and from radioactive isotopes decaying in the Earth's crust.

This geothermal energy originates from the original formation of the planet, from radioactive decay of minerals, from volcanic activity and from solar energy absorbed at the surface.

Even in the Earth today, radioactive decay generates about 20TW of energy.

We have the increase in atmospheric temperature from nominal forcing and the increase from energy introduced into the system from combustion and radioactive decay in the mantle.

The energy is — especially if we add internally generated heat from radioactive decay in the mantle — sufficient to increase the temperature of the atmosphere to the higher temperature without having a «radiant imbalance» at TOA at all.

Since energy is constantly being added from the decay of the radioactive elements in the planet's core, the temperature inside a perfect reflector would rise until the reflector melted.

Same for radioactive decay of elements in the earth, and I even calculated the energy released by burning of fossil fuels... in the end, all insignificant.

Geothermal energy is created using the heat from within the Earth's core that comes from the radioactive decay of minerals.

We should study all aspects of climate, including the most important source of energy into our world climate system (the only other being radioactive decay heat, I believe) a little longer before we make simplifying assumptions that lead us to stupid answers (such as CO2 is the only thing that affects world climate — which is effectively what the IPCC and green lobby asserts today regardless of how much they weasel word it if pressed.)
