Tenders Are Invited For Monitoring Of Ionizing Radiation Carried Out As Part Of The State Environmental Monitoring In 2026-2027. Task 3: Monitoring The Concentration Of Cesium-137 In The Soil

1. The Task Is To Determine The Current Distribution Of Caesium-137 Deposition And The Concentration Of Natural Radionuclides (Radium-226, Actinium-228 And Potassium-40) In The Surface Layer Of Soil. The Measurement Program Includes The Collection Of No Less Than 134 Soil Samples From Six Selected Voivodeships (Lower Silesia, Lesser Poland, Masovia, Opole, Silesia, Świętokrzyskie) At 130 Points Located In The Meteorological Gardens Of Stations And Posts Of The Institute Of Meteorology And Water Management - National Research Institute (130 Samples From The 10 Cm Thick Surface Layer And 4 Samples From The 25 Cm Thick Layer). Determination Of The Concentrations Of Cs-137 And Natural Radionuclides (Ra-226, Ac-228 And K-40) In The Collected Samples. Measurements Are Performed Using The Semiconductor Gamma-Ray Spectrometry Method Approved By The President Of The Paa.2. A Detailed Description Of The Subject Of The Order And The Method Of Its Implementation Is Included In Annex No. 8 To The Swz - Description Of The Subject Of The Order. This Description Should Be Read Together With Changes In The Content Of The Swz, E.G. As A Result Of Responses To Contractors Inquiries.
