The pollution areas, radiation type and nature, equivalent dose of -rays and exposure dose rate is determined by dosimeters and the prospecting for radiactive materials and ionizing sources are realized.
This is conditioned to a high extent by the fact that scintillation materials differ for their high registration efficiency, sufficient temporal and energy resolution.
Scintillation semiconductor detectors (SD) on the base of metal-А 3В 6 lamellar semiconductors are perspective materials for electron, x- and γ-irradiation.
Introduction SDs are the most perspective materials in optoelectronics because of the small size of an active area and the possibility of providing high sensitivity by means of a highly active area creation [6].
Scintillation SDs on the base of metal - А 3В 6 lamellar semiconductor are perspective materials for electron, x- and γ-irradiation.

These fibrous lignocellulosic materials, after meeting the field soil enrichment requirements, represent a substantial source of biomass that holds the promise for nonfood-based biofuel for present and future energy needs [7].
Shearing was proved to be the energy efficient method for cutting fibrous lignocellulosic materials.
It was concluded shear failure is expected to be more energy efficient than tensile failure for cutting fibrous materials.
This phenomenon indicates that the bionic saw blade has potential extension to cut other biomass materials with fibrous lignocellulose and may hold promise for improved energy efficiencies.

They can be used such as wound dressing [1], materials for drug delivery system [2], electrically conductive nanofibers [3], nanofiber composites [4] or materials for filtration [5].
In this process, two liquid materials are delivered independently through a special coaxial capillary, i.e. spinneret.
Different kinds of materials can be successfully electrospun by this special technology.
These aspects bring heavy demands on the feasibility of materials and manufacturing processes.

Introduction Compared with traditional metal materials, such as steel, aluminum and titanium, composite materials are used extensively in marine and aerospace structures due to their higher specific strength and specific stiffness, lower density and flexibility in design.
At present, laminated composite materials are the main practical application of composite structure.
Different materials have different loss factor, so that how to make the kinetic energy of oscillation converting to other forms of energy (for instance, heat energy, deformation energy), and how to make the system restore pre-stimulated state are the considerations during the design of laminated composite materials structural.
During the design of material structure, choosing the relatively low fiber volume fraction of the structure can improve the damping property of laminated composite materials.

In addition, due to the excellent strength, high temperature stability, and corrosion resistance, hard passive alloys, such as nickel-based super-alloys, titanium and molybdenum alloys are widely used as aero-engine blade materials.
At present, electrochemical machining (ECM) has been developed as a main method for machining difficult-to-cut materials and shaping complicated contours and profile.
Being a non-mechanical metal removal process, ECM is capable of machining any electrically conductive materials with high stock removal rates regardless of their mechanical properties, such as hardness, elasticity and brittleness.
