Radiation: a poly-traumatic hit leading to multi-organ injury

Cell & Bioscience

Table 1 Characteristics of nuclear radiations [135]

Name	Relative mass	Electric charge	Emitted by	Range in air	Tissue penetration	Radiation stopped by
Alpha	7300	+ 2	Unfissioned uranium and Plutonium	5 cm	First layer of skin	Clothing paper
Beta	1	− 1	Fission products	12 m	Several layers of skin	Clothing
Gamma^a	0	0	Fission products	100 m	Total body	Several feet of concrete or earth
Neutron	1830	0	Emitted only during fission	100 m	Total body	Several feet of concrete or earth

^aFor the purpose of this presentation X-rays are considered along with gamma rays. X-ray wavelength bands largely overlap those of gamma rays, and they interact at least mechanistically like gamma rays. They are now usually distinguished only by their origin
