Using Irradiation To Make Food Safer For Consumers
1,173 words... the product and not in all directions, the electron beam is more efficient. A ten kilowatt beam generator is as powerful as about one-million curies from a cobalt- 60 source (Murano 14 - 15). The electron accelerators produce from five to ten million electron volts and ten to fifty kilowatts (Murano 15 - 16). The electron beam efficiency can be increased by aiming the beam at a metal target, usually tungsten or tantalum. This produces Bremsstrahlung x-rays. This type of x-ray can penetrate a...

Hubble Space Telescope Universe Continues To Expand Energy
786 wordsThe universe begins with a cataclysm that generates space and time, as well as all the matter and energy the universe will ever hold. For an incomprehensibly small fraction of a second, the universe is an infinitely dense, hot fireball. The prevailing theory describes a peculiar form of energy that can suddenly push out the fabric of space. On a rare occasion, a runaway process called "Inflation" can cause a vast expansion of space filled with this energy. The inflationary expansion is stopped o...

Army Corps of Engineers, because a lot of it's earlier research was done in New York City. An atomic bomb is a weapon that uses the energy from a nuclear reaction called Fission for its destruction. The idea that mass could be changed into energy was predicted by Albert Einstein in the earlier part of the 1900 's. John D....
