Ecological policy of Leningrad NPP is aimed at ensuring minimum effect on the environment

In Jan 2008 the radiation situation in the buffer and monitoring zones of Leningrad Nuclear Power Plant was within norm, which proves that the plant and its facilities have no negative effect on the population and the environment of its nearby area.

Last month the emission of radioactive gases and aerosols was as follows:

• neutral radioactive gases – 0.43% of admissible level;
• iodine-131 0 0.20%;
• cobalt-60 – 1.04%;
• cesium-134 — 0%;
• cesium-137 – 2.22%.

The concentration of radio-nuclides in the air of the buffer and monitoring zones made up just 0,001% of the admissible average annual levels for relevant radio-nuclides.
 
No release of radioactive liquid waste into Kopora Bay of the Gulf of Finland was registered in Jan 2008.

The gamma radiation background at Leningrad NPP and in the nearby area was within norm.

In Jan 2008 the maximum gamma background in the area monitored by the automated radiation control system made up 0.20 mSvh.

Note

Leningrad Nuclear Power Plant has an automated system for monitoring the radiation situation in its buffer and monitoring zones.

The plant also has a complex for monitoring the radiation background of the nearby waters (sea water and water in the waste canals of the plant). The complex consists of two floating control stations situated in the waste canals of all the four units of the plant.
