Information about the characteristics and permissible concentrations of radionuclides in air and water.
Table D.2.1 - Permissible levels of intake of radionuclides through inhalation DNinhal And allowable concentration in the air of working premises DKinhal And for category A *
Acceptable receipts through inhalation (DNinhal A DNinhal B DNinhal B, or in general DNinhal) - annual intake of radionuclides through inhalation (acceptable level), which provides exceed the dose limit for any combination of age, AMAD and type compound inhalovanoyi impurities. For staff only considered the reference age "adults."
Permissible Level (PL) - the original standard for intake of radionuclides in the human body for the calendar year, averaged per year equivalent dose, concentrations of radionuclides in air, water and diet particle flux density, etc., intended for reference conditions of irradiation values of dose limits.

Radiation safety - state radiation and nuclear facilities and environment that provides for avoiding the basic dose limits, excluding any undue exposure and reduction in personnel and the population below the dose limits as far as this can be achieved and economically justified.
Radiation weighing factor - a factor that takes into account the relative biological effectiveness of different types of ionizing radiation. Used when calculating the effective and equivalent doses.
Table D.11.1 - Values radiation weighing factors (WR)
| Type of radiation | WR |
| Photons, all energies Electrons and muons, all energies Protons with energy> 2 MeV Neutrons with energies <10 keV with energy 10-100 keV with an energy of 100 keV to 2 MeV with energies 2-20 MeV with energy> 20 MeV Alpha radiation, heavy recoil nucleus | 1 1 5 5 10 20 10 5 20 |
Radiation risk - the likelihood that a person as a result of exposure there some stochastic effect.
Radiation factor (exposure)- Any type of radiation, which results or may result in human exposure or contamination of the environment.
The dose equivalent to the organ or tissue T (Ht)- the value of which is defined as the product of the absorbed dose DT in a single organ or tissue T for radiation weighing factor WR:
Ht = DT – WR
The unit of equivalent dose in the CI - sievert (Sv). 1 Sv = 100 rem.
Effective dose (E) - the sum of products of equivalent doses of Ht in individual organs and tissues to the corresponding tissue weighing factors WT:
E = Sum T x W T
Using the concept of effective dose allowed for values of equivalent doses are in the field values below the threshold of deterministic effects.
