Abstract
Material for shielding against ionizing radiation. X rays and γ rays are best absorbed with high-Z materials (e.g. lead or tungsten). The absorption of neutrons is best done with substances containing a high fraction of hydrogen. Neutrons can also be captured in boron or cadmium. α rays are of very short range and can be stopped even with thin foils. β rays should be absorbed with low-Z materials (1 cm aluminum or 2 cm plastic) to avoid bremsstrahlung.
“A good notation has a subtlety and suggestiveness which at times make it almost seem like a live teacher.”
B. Russell 1872–1970
