[Results of measuring neutrons doses and energy spectra inside Russian segment of the International Space Station in experiment "Matryoshka-R" using bubble detectors during the ISS-24-34 missions].

The paper presents the results of calculating the equivalent dose from and energy spectrum of neutrons in the right-hand crewquarters in module Zvezda of the ISS Russian segment. Dose measurements were made in the period between July, 2010 and November, 2012 (ISS Missions 24-34) by research equipment including the bubble dosimeter as part of experiment "Matryoshka-R". Neutron energy spectra in the crewquarters are in good agreement with what has been calculated for the ISS USOS and, earlier, for the MIR orbital station.

[Methodological approaches to the training optimization for students in radiation hygiene].

In the article the psycho-pedagogical and physiological-hygienic aspects of improvement of student's learning in radiation hygiene at the Health-prophylactic Faculty of the medical institution within a framework of the requirements of the new Federal State Educational Standard -3 are considered.

The paper considers the topical hygienic aspects of education and adaptation improvement in senior (fourth-year) medical students from the Faculty of Medical Prevention.

[Results of measuring neutron dose inside the Russian segment of the International Space Station using bubble detectors in experiment Matreshka-R].

Distribution of neutron equivalent dose both inside and outside the spherical phantom (experiment Matryeshka-R) was determined with the help of dedicated research equipment "Bubble-dosimeter". Equipment is built up from an automatic bubbles counter and 8 bubble detectors of neutrons with energy ranging from approximately 200 keV to 15 MeV. Measurements inside the ISS were made in several 7-day sessions in the period from April 2006 till October 2007 (ISS increments 13-15).

[Some results of radiaton monitoring of the ISS Russian Segment in 2000-2005].

Dynamics of the ISS RS radiation environment was studied using the data of daily (operative) monitoring and personal dose measurements during 11 increments in the period between August 1, 2000 and October 28, 2005 overlapping the maximum phase of the 23rd solar cycle. It was shown that personal absorbed doses varied within the range of measurements of dual wavelength radiometer R-16, a component of the ISS radiation monitoring system. Power of the absorbed doses fell in the range of 0.
