1. Abstract
Recently, for increasing of radiation material`s use, shielding material`s
development is required. In this monograph , add B, Al, H..etc to polymer
materials in order to improve special quality about Radiation shielding
materials and its shielding capacity. And prevent decreasing of shielding
capacity as removing oxygen which take place in material instrument. At the
same time, increasing shielding`s role as changing atomic bonding`s
structure. Also, look analysis of atomic number density and macroscopic
removing cross section in radiation shielding capacity. This radiation
shielding material`s field is insufficient yet in the actual circumstances. So,
many developments are more required.

2. Introduction
「Usually, alpha, betta, gamma-line, and neutron are the main radiation.
And it always takes place when power station is working. Gamma-line has
big material penetration effect. So, control addition or humidity, pressure,
and temperature`s condition to prevent its penetration. A neutron`s energy
and penetration are very high. Also, a neutron has take place the second
gamma-line in n-gamma`s reaction, so the second gamma-line can harm
human`s body. So, neutron shielding materials have been developed to
prevent neutron safely. Recently, neutron shielding material composed with
polymer materials as the main materials is in developing step in USA and
Japan.」[1][3]
