Many smoke detectors contain?
a. Americium-241 Smoke detectors might have an ionizing chamber. If it does, the chamber holds a radioactive nuclide to ionize the particles in the smoke to set off the detector. Usually the radioactive source is americium.
One example of this heat is the sun?
The sun is our main source of heat but also the Earth generates some heat as a reuslt of radioactive decay in the mantle.
How can friction become negligible?
because it is a source of energy and it is dissipated of heat
What is the source of heats earths interior?
The heat present in the Earth is due to several factors. The first source of heat is from the remnants of heat from impacts with planetesimals early in Earth's history. Impacts with large bodies such as these (including the impact which led to the formation of the moon) trapped the thermal energy of the collision in the surrounding rock of the planet, and may have been enough in certain circumstances to completely melt the early Earth. The second source of heat is also a remnant of an early Earth event known as the Iron Catastrophe. With much of early Earth still molten, denser metals, particularly iron and nickel, migrated to the center of the planet. Tremendous amounts of frictional heat was created, enough to completely melt the planet once again. The third source of heat in the Earth is from compression due to gravity. The fourth and final source of heat in the Earth is from the decay of radioactive elements. This source of heat is gradually declining due the decreasing amounts of radioactive isotopes, the decrease being caused by the decay.
When an emergent theory becomes a consistent and recurring source of research and becomes comprehensive and widely applied it has become what theory?
grand
What is the modern source of protactinium element?
- from irradiated thorium - from uranium ores residues
WHAT DOES The amount of radiation that an individual absorbs depends on?
Time exposed to a radioactive source and the Distance a person is from a radioactive source and Type and amount of shielding between a person and a radioactive source.
What is sealed and unsealed radioactive source?
sealed radioactive source means the radioactive isotopes which is encapsulated with a stainless steel to avoid higher LET radiation condamination .typically source may be used in brachytherapy to treat the cancer and unsealed source used to in nuclear medicine which is the radioactive source is not sealed examble IODINE131
What is the source of heating in the mantle?
Source of heat in mantle come from radioactive decay of the radioactive elements inside the earth..

What is packed red blood cell 'irradiated' mean?
After separating the red blood cells from the donated blood, they are irradiated with a gamma source. Irradiation is used to minimize the chance of transfusion-associated graft-versus-host disease.
What mineral is probably the source for radioactive isotopes derived from nuclear reactors?
uranium is probably the source for radioactive isotopes derived from nuclear reactors
Where gamma ray Originates?
by radioactive source

You do not. You do deliver it to those who can.
Where do gamma rays originate?
