The materials used to manufacture these containers have radiation-protective properties, which are characterized by the following comparative values of mass attenuation factors of γ-emission, cm2/g:
Energy, keV Protective properties Steel Lead
59.5 1.152 1.072 4.241

Tests of these items under the influence of solar radiation, oxygen, high humidity and industrial gas pollution over 30 years have resulted in little or no corrosion. Marine tests over five years resulted in less than 10 % decrease of stretching and compression breaking point, for module of elasticity Æ less than 6 % decrease.


3. Rubberized fabric for protection against radiation
(TU U 25.1-31655768-001-2005)
Rubberized materials with radiation-protective properties for the manufacture of personal protective clothing and equipment. Currently being used during installation work on the Chernobyl SHELTER facility.
Materials provide protection from:
  • Direct contamination of radioactive wastes;
  • Radioactive α- and β-emission - entirely;
  • Highly penetrative roentgen and γ-emission- partly;
  • Chemically and bioactive substances.
Clothes from rubber protective material are airtight, used as additional PPE and can be worn over standard overalls and with special footwear when carrying out repair, installation and decontamination work. Protection clothing made of rubberized radiation-protective fabric are very elastic and have a very low weight coefficients when compared to articles made of lead-based materials.
Radiation-protective properties of rubber material for PPE:
Density, g/cm3 Linear attenuation coefficient, cm-1
241Am 137Cs 60Co
60 keV 661 keV 1,210 keV
2.12 2.5120 0.235 0.146

The thickness of one layer of radiation-protective rubberized fabric is 0.8 mm.
Rubberized fabric for protection against radiation can also be used for the manufacture of collective protective equipment including: folding screens and shields. For instance, radiation-protective shield of 0.5 m2 and 20 mm thick weights 20 kg and has the following radiation-protective properties:
Attenuation decrease on energy of 137Cs (661) - 1.622
Attenuation decrease on energy of 60Co (1210) - 1.35
It is also possible to produce these materials in fire proof form


4. Polyvinylchloride film for protection against radiation
(TU U 25.1-31655768-003-2004)
Radiation-protective properties:
Density, g/cm3 Linear attenuation coefficient, cm-1
241Am 137Cs 60Co
60 keV 661 keV 1,210 keV
2.04 2.481 0.191 0.156

Materials based on PVCh (polyvinylchloride) are one of the most widely used materials for protection against radiation. They are used for the manufacture of personal protective equipment and clothing (suits, coveralls, gowns, cover-suits, jackets, raincoats, gloves etc.), as well as elastic folding screens, shields and screens. This material was developed by 'Yuzhmash' for use in the former Soviet space program and uses specially modified agents based on super- dispersed materials technology that greatly increases the radiation-protective properties of the material compared to its initial condition.
Clothing made of PVCh is airtight, used as additional PPE and is worn over standard overalls and with special footwear when carrying out repair, installation and decontamination work at nuclear power plants.
The thickness of one layer of PVCh radiation-protective material is 0.4 mm.
It is also possible to produce these materials in fire proof form


5. Radiation-protective glass-fiber plastic
Radiation-protective fiberglass plastic is intended for the manufacture of hard screens, shields, elements of external and internal coatings and quick-assemble structures including passages, temporary facilities and walls.These composite materials have been used for many years in rocket production have proved their high mechanical strength, chemical resistance and light weight application. Research conducted at Kharkov Physical-Technical Institute has shown that radiation resistance of the composite material will remain for not less than 300 years.
Articles manufactured of composite radiation-protective glass fiber plastic have the following properties:
Radiation-protective properties
Linear attenuation coefficient on the energy 137Cs (662 keV), cm-1 0.287
Density, g/cm3 1.78

It is also possible to produce these materials in fire proof form
