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 posterities

The 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

Thanks for attention!!!
