Radon protection
We offer technology of protection against radon with Abris sealants.
Radon is a chemically inert radioactive gas that has no smell, color, or taste. In the air, radon breaks up into short-lived daughter products (isotopes). They emit alpha particles with high ionizing power and attach to dust and other particles contained in the air.
Ways of radon penetration into the house
Advantages of Abris S insulation technology:
- Reduction of concrete consumption.
- Maintaining the continuity of the insulation coating at possible deformations in the concrete pad due to the plastic properties of the material Abris S.
- Reduced penetration of radon into the room.
- Cold application (no material heating).
Comparative radon-protecting characteristics:
| Material, medium (2mm layer) | Radon diffusion coefficient D, cm² / s | Radon diffusion length, L, cm |
| Air | 1,0*10-1 | 75,00 |
| Water | 1,0*10-5 | 0,75 |
| Heavy concrete | 3,5*10-4 | 4,30 |
| Light concrete | 1,4*10-3 | 8,60 |
| Brick | 4,7*10-4 | 5,00 |
| Abris S | 0,42*10-6 | 0,15 |
* According to the results of the tests of FSUN "St. Petersburg Research Institute of Radiation Hygiene named after Professor P.V. Ramzaev."
The efficiency of reducing radon flow with Abris materials is an order of magnitude higher than for heavy concrete and brick and noticeably higher than for water. The length of radon diffusion in the Abris material is 30 times lower than the length of radon diffusion in heavy concretes and 5 times lower than in water.
