CONTENT

1. Brief historical introduction and problem actuality

2. Decrease by UNSCEAR of low dose radiation limit twice and its unification with other international organizations

3. Ambiguity of a substantiation of low dose radiation limit in 100 mGy

4. Absence of the proved molecular mechanisms and experimental confirmations of an induction of stochastic effects at doses up to 100 mGy

5. A new dose range – very low doses (up to 10 mGy)

6. Medium, high and very high (super-high) doses

7. Concepts about low dose rate

Conclusion

Key words: radiation dose ranges, low doses, very low doses, middle doses, large doses, low dose rate, definition, low LET radiation
