%X The <span lang=\"SQ\" style=\"font-family:Verdana;\">Ionising
irradiations used mostly in the treatment of tumoral diseasses are: X, ¦Ã, ¦Â and
e irradiations. The discussion will be about ¦Ã irradiations, produced in linear
accelerator with photon energy 6 MV and 15 MV. It is important to know the
absorption performance before and after the electronic equilibrium. This is a
reason that we¡¯ve used the function of dose gradient for irradiations ¦Ã. It
represents the velocity of dose change as a function of depth in tissue. From
skin to maximum dose value, the increase of G-function is more accentuated for ¦Ã-rays
than for ¦Â-particles while after that the G-function decreasing is less sharp
for ¦Ã-rays. Finally, we¡¯ll discuss about the advantages in terms of radiation
protection of ¦Ã-rays used in radiotherapy.</span>
