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

The 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...

people think. The chances of a meltdown or a
radiation leak are extremely small. There are many
safety features, which make nuclear power one of
the safest electricity sources. And every nuclear
power plant is protected with thick layers of
steel and concrete. Nuclear power is also very
environmentally friendly. It produces hardly any
air pollution, and it releases less radiation into
the atmosphere than coal...
