GAMMA
RAY STERILIZATION
Gamma
radiations are electromagnetic waves uttered by unstable
isotopes (radioisotopes) through the phenomenon of "
decadence " or " disintegration " called
Radioactivity.
The number of disintegrations in the unity of time defines
the activity of the radioactive source. The radiation, crossing
the matter, surrenders a certain quantity of energy to this.
The absorbed dose is the energy surrendered to the matter
radiated in the unity of mass.
The unity of measure for the absorbed dose is the Gray (Gy)
correspondent to 1 J/kg.
60Co is the radioisotope gamma emitter more largely used
in the industrial trials of irradiation and drift from the
bombardment 59Co neutronic existing in nature.
The effects, direct or induced, of the radiations on the
micro - organisms consist in their interaction with the
nucleus of the cells and other components, causing the break-up
of the molecules of the DNA and preventing the cellular
division and therefore the propagation of the biological
life (microbial proliferation).

Sterilization Company present today in Italy.
