Absorber
 scroll 
Any material "stopping" ionizing radiation.
Alpha radiation can already be totally absorbed by a sheet of paper;
beta radiation is absorbed by a few centimetres of plastic material
or 1 cm of aluminium. Materials with a high atomic
number and high density are used for gamma radiation absorbers (lead,
steel, concrete, partially with special additions). Neutron absorbers
such as boron, hafnium and cadmium are used in control rods for reactors.
