PURPOSE:
- Investigation into dynamics of in-orbit radiological
situation both in Service Module and the ISS RS
docking module, as well as accumulated radiation
doses in anthropomorphic and spherical phantoms.
- Improvement of the methods of space dosimetry
and evaluating radiation hazard impact on cosmonaut's
body during dynamics of radiological situation throughout
flight trajectory.
OBJECTIVES:
- Measurement of spatial and solid distributions
of radiation characteristics of space ionizing radiation
in pressurized compartments of Service Module and
Docking Module of the ISS RS by means of scientific
equipment PDA (Assembly of Passive Detectors) and
Phantom (Spherical Tissue-Equivalent Phantom).
- Development of calculation methods to evaluate
radiation doses for various organs of cosmonauts'
bodies during long in-orbit flights to the ISS RS.
- Verification of radiological situation models
in near-earth space and the methods for calculating
radiation transmission through protective substance
and tissues by comparing the assessed parameters
of radiological conditions determined via calculations
in the station compartments and phantom with the
measurement results.
- Research into space radiation distribution throughout
the station flight trajectory.
- Study of time-dependent space radiation variations
(cycles of solar activity, proton emission resulting
from sun burst) and in-orbit parameters.
- Research into impact of protection on variation
in space radiation dose (attenuation of dose, factor
of protection substance accumulation and/or activation).
EXPERIMENT RESULTS:
- PDA kit assemblies with the exposed detectors.
- Stowage of the Phantom scientific equipment containing
cylindrical cases and the cover with the exposed
detectors within it.
- Photographic data to be downlinked via TV exchange
module.
- Data necessary to predict radiation hazards risk
for future space projects and to develop the ISS
radiation monitoring aids.
