USED SCIENCE HARDWARE:
The experimental hardware includes three separate
modules:
- An irradiation module (UV radiation camera)
The UV radiation camera contains a biological material
in NaCl solution (0.9%), which is distributed by four
grooves (by 1ml). UV light with a wave length of 375
nm is generated by light-emitting diodes. The bacteriological
solution contains nonpathogenic bacteria, which are
derivatives of Escherchia coli K12.
- An electronic control module (with a set of cables)
serves to supply power to the irradiation and
ventilation modules, as well as to control the process
parameters.
is designed to cool the UV camera, electromagnetic
interference filter and voltage regulators of the electronic
control module during the process of exposure to radiation.

PURPOSE:
To study the effect of high level radiation on DNA
reparation mechanisms in microgravity conditions.
OBJECTIVES:
To study the UV-radiation effect (375 nm) on bacterium
Escherichia coli й12 DNA reparation in microgravity
conditions.
EXPERIMENT RESULTS:
Biomaterials exposed to UV radiation and experimental
data recorded in the memory module.
