[en] In this leaflet the results of monitoring of chemical gaseous and liquid effluents into the rivers Vah and Dudvah as well as of radiation monitoring of Bohunice V1 NPP, Interim Spent Fuel Storage (MSVP), Bohunice Radioactive Waste Processing Centre (VK808 - BSC), The Main Production Unit (VK 46A - HVB) and Bitumenation Lines (VK 46B - BL) are presented. The radioactive effluents into atmosphere within January - May 2012 (for NPP V1, MSVP, BSC, HVB and BL, respectively) were: 0.341 MBq (0.000% of AL) for V1, 0.232 MBq (0.078% of AL) for MSVP, 0.159 MBq (0.113% of AL) for BSC, 1.306 MBq (0.199% of AL) for HVB and 0.061 MBq (0.043% of AL) for BL of aero-soles. The radioactive effluents into atmosphere and hydrosphere within a May 2012 for NPP V1, MSVP, and VK 808 BSC, respectively, were: 0.066 MBq (V1), 0.106 MBq (VK MSVP), 0.031 MBq (VK 808 BSC), 0.231 MBq (VK 46A) and 0.011 MBq (VK 46B) of aero-soles into atmosphere; 1.221 MBq (V1 and MSVP) and 4.721 MBq (TSU RAO and NPP A1) of corrosive and fission products, and 0.006 GBq (V1 and MSVP) and 6.318 GBq (TSU RAO and NPP A1) of tritium into the Vah River and 0.000 GBq (V1 and MSVP) and 0.036 MBq (TSU RAO and NPP A1) of corrosive and fission products and 0.0 GBq of tritium (V1) and 0.000 GBq of tritium (TSU RAO and NPP A1) into the Dudvah River). For the period January - May 2012 these radioactive effluents into recipient of Vah River represent for corrosive and fission products 5.170 MBq (0.040% of AL for V1 and MSVP) and 28.595 MBq (0.238% of AL for TSU RAO and MSVP); and for tritium it is 5.533 GBq (0.277% of AL) for V1 and MSVP, and 80.959 GBq (0.810% of AL) for TSU RAO and NPP A1 (into the Vah River) and for corrosive and fission products 0.000 MBq (V1) and 0.470 MBq (TSU RAO and NPP A1) (0.392% of AL) and 0.000 GBq (0.000% of AL) for V1 and MSVP and 0.000 GBq (0.000% of AL) (TSU RAO and NPP A1) of tritium (into the Dudvah River). Chemical effluents are reported, too.
