received first during the exposure. The properties play
an important role in nuclear interaction of photon like
X-rays or γ radiation is the density of material where
the these radiation have passed through. These radi-
ations will interact more with the high density materi-
als because because lots of radiation will reduce dur-
ing the interaction. In the case of neutron, a neutron
cross section of material determines the interactions
with neutron. Large neutron cross section material has
high probability to interact with neutron, hence the in-
teraction become higher in this kind of material. The
possibility to damage more is higher compared with the
material that neutron just has passed through.

From the radiation protection perspective, info on
the damage into human body created upon the inter-
action with ionizing radiation is important. This infor-
mation is used to develop program or plan of work in
order to minimize damage into the personal. The ab-
sorbed dose whether in Gray or rad does not tell the
severity of damage because it is dependent on the ra-
diation type and energy. In this purpose, the effec-
tive dose defines absorbed dose that created an actual
damage with similar severity even though the different
radiation source and material. The effective dose (H)
in rem is defined in Equation 6.3. Where QF is the
Quality Factor which describe degree of damage due
any radiation given in absorbed dose rad that produce
the same damage as 1 rad of X-rays or γ radiation.
