Radiation Effect on living body
Alpha, Beta and Gamma particle
Alpha – Two protons and two neutrons
Beta – Electrons
Gamma – High energy electromagnetic irradiation
Nuclear power plant
Effects of radiation on the human impact
1. Somatic (bodily) – is formed in the body of an irradiated man.
2. Genetic – is related to the damage of a genetic apparatus and manifests itself in generations of an irradiated person: in children, grandchildren, grandsons and in other more further posteritiesThe radioactive effects of irradiation of a man
Somatic effect Genetic effect
Radiation disease Genetic mutation
Local radiation damages Chromosome aberrations
Leucosis
Tumors of various organs
The people at irradiation doses and result
Influence of various doses of irradiation on the human body
Dose, gr Causes and results of influence
(0.7-2) •10-3 The dose received from natural sources per year
0.05 The boundary admitted professional irradiation dose per year
0.1 The probability level of doubling of genetic mutation
0.25 The single dose of a justified risk in an extreme situation
1.0 A dose of appearing of an acute radiation disease.
10-50 The irradiated person dies in 1-2 weeks, mainly because of damage of alimentary tract
100 The irradiated person dies in several hours, or days because of damage of central neurotic system
