In this paper we have exposed 3 HD cameras with CMOS sensor in long time experiment at different doses and exposition time with γ radiation from 2 sources of ionizing radiation – cobalt 60 (Co60) and cesium 137 (Cs137) at room temperature imitating the working conditions of “hot cell” premises. All components of the used camera are without radiation reinforcement, excluding the lenses. During the experiment, we found degradation of the irradiated cameras. As the absorbed dose increases, the image becomes brighter. Furthermore, experimental results demonstrated decreasing in signal-noise ratio (SNR) with increasing the absorbed dose. We confirmed that the HD
industrial cameras can operate in ionizing radiation environment with moderate decrease of

In the process of decommissioning of nuclear power facilities large metal waste quantities are generated which have to be processed in an appropriate manner. An optimal approach, adopted in a world-wide scale, is their meltdown at the final stage of treatment. Depending on the residual radioactive contamination, metal obtained thereafter may be directed for application in the industries, without limitations, or used on restricted purposes (production of radioactive waste containers, bio-protection means, etc.).

As a result of the use of roller skates for recreation or sports on uneven surfaces other than a special one, there is a significant amount of mechanical energy absorbed by the frame of the skates as a result of unevenness, as well as combinations of jumps and landings from different heights. Scientific study on this issue will provide an opportunity to gain an insight into how much mechanical stress is distributed to а skate frame and to determine under what conditions the frame will be destroyed.
