The purpose of this work is to improve the Russian Radiation Safety Standards (NRB) in terms interpretation meaning “the main limit annual effective dose” and use concept “emergency”. In [1], proposals were submitted discuss changing new versions NRB Main Health Rules for (OSPORB) dose man-caused occupational exposure” health physics regulation radionuclide contents solid materials free or limited these materials. current NRB-99/2009 uses term “radiation accident” establishes limits (Table...

Purpose: Harmonization of the Russian Federation legislation with current international recommendations
 Results: The concept radiation safety system has been significantly modified by recommendations ICRP (2007) and IAEA (2014). An analysis existing regulatory framework for allowed to identify main provisions be implemented in legal framework. It’s showed that Federal Law 09.01.1996 No. 3-FZ «On Radiation Safety Population» must ultimately revised harmonized documents. General...

This article covers basic issues of the radiation protection in nuclear industry. It contains an overview history national industry including creation industry-specific facilities (research centers, medical units etc.). Main stages creating regulatory system for protection, starting from beginning industrial introducing exposure limits and implementation international documents are described. In 1996, first time, requirements Russia were documented form Federal Law 3-FZ 09.01.1996 “Radiation...

The design of permanent joints with fillet welds characterized by bevelling the edges depth decreasing an increase in distance from weld edge to centre is proposed. experimental results show that producing bevel variable depth, volume deposited metal reduced 35% corresponding reduction material requirement process without reducing load-carrying capacity welded joint.

Purpose: To adapt traditional method of soft beta emitters’ dose calculation to the individual biological cells, estimate value absorbed dose-rate factors for different tritium compounds on a cellular level. Material and methods: Approximation point-source function obtained by L.V. Timofeev, G.B. Radzievsky et al. was used macroscopic beta-particle dosimetry methods area subcellular structures. Results: Using introduced concept irradiated cell model base states analytical expressions in...

Tritium is one of the most important dose-forming radionuclides that determine radiation situation in area where nuclear fuel cycle enterprises are located. At same time, it not possible to catch tritium formed during operation a power plant using modern, efficient and cheap technologies. This causes an increase its concentration environmental objects contribution technogenic load population. Therefore, task monitoring formation plants, content emissions discharges as well distribution this...

Purpose: To summarize and analyze the results of research practical recommendations on decontamination victims in event radiation accidents, including taking into account authors’ experience gained initial period Chernobyl accident (April – August 1986) other local accidents (incidents), as well during emergency exercises.
 Results: The indications for carrying out technique its implementation were considered, a comparative assessment effectiveness skin agents was presented....

The design of permanent welded joints with fillet joints, characterized by the bevelling edges depth decreasing an increase in distance from edge joint to centre, is described. It shown that when producing bevelled variable depth, volume deposited metal can be reduced 35% corresponding reduction production costs process without reducing load-carrying capacity joint.

Introduction: 14C is one of the fifteen radionuclides that account for at least 99 % radiation dose to critical group population from NPP emission sources. The continuous growth total capacity operating NPPs leads a significant increase in amount 14С emitted into environment during operation. Efficient capture and disposal 14C, which has half-life 5760 years, very laborious undertaking. At same time, due high mobility this radionuclide, local foci contamination with can appear both near...

The stress state of welded joints in pipelines with spherical defects is analysed. It shown that biaxial loading conditions, characteristic the operation internal pressure, theoretical intensity factor kσ = 2.1. also safe a pipeline can be ensured by placing band guaranteed interference magnitude which should determined to ensure maximum service stresses defective area do not exceed limit destruction material joint.

 Material methods: The following researches were conducted during assessment radiation hygiene situation:
 - assessing the state physical barriers repositories (tanks) solid liquid RW;
 situation at repository site before after remediation;
 measuring specific activity 90Sr 137Cs in ground subsurface water, core sample, soils, building...

The article covers issues related to the specifics of requirements for personal protection equipment (PPE) in field nuclear power usage, and briefly describes history PPE evolvement. This work was performed by employees A.I. Burnazyan Federal Medical Biophysical Centre (former Institute biophysics) which has been creating enhancing personnel radiation hazardous facilities more than 60 years. Successes developers include creation light respirator “ShB-1 Lepestok” use since 1950s till now...

Computational for determining effectiveness radionuclide registration presented. Results possibility gamma-ray spectrometry assess materials contaminated with α-emitters...

The article is devoted to the substantiation of need implement a special program radiation-hygienic support work with nitride fuel for fast neutron reactors. It shown that at current pace implementation project direction "Breakthrough", in conditions when achievements scientific research lead revision design and technological solutions, it possible manage radiation hygiene only mode provides quick response changes real production environmental situation.

Purpose: Analysis of the current regulatory and methodological framework on control doses from intake 14C for personnel public living in area nuclear power plant (NPP). Identifying most informative methods controlling radiation impact a human being. Material methods: Research literature naturally occurring 14C; entering environment as result weapon tests; workplaces NPP has been reviewed. Dose coefficients other characteristics provided IAEA, ICRP UNSCEAR publications have summarized....
