The electronic cotrol module serves to supply power to the irradiation and ventilation modules, as well as to control the process parameters. A ventilation module 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.Operational Protocols
To study the UV-radiation effect (375 nm) on bacterium Escherichia coli E12 DNA reparation in microgravity conditions. 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.
Biomaterials exposed to UV radiation and experimental data recorded in the memory module.
