KUDOS – this is Epic work you’re doing here guys I can’t say that enough. I’ll be re-posting this minutes from now in the interest of distribution and broad publication. One thing I’ll include in the re-post is this ‘interactive isotopic periodic table’ that shows – INCLUSIVELY – each and EVERY isotope that travels with each other and their Daughters and Actinides. Tritium travels with almost 2K+ other isotopes as an inseparable ‘group’ (they’re GangBangers) and they CANNOT be isolated or separated easily, if at all, from each other – not today anyway! I think people will get a much better idea of the “CARNAGE” being caused by the Nuclear Crime Syndicate worldwide but using this simple chart.. https://periodictable.com/Isotopes/096.247/index.full.html

The 2006 impact assessment for the landfill, before opening, assumed that the activity limit for radioactive waste in the Calder Floodplain Landfill Segregated Area (CLESA) would be 37,000 Bq/kg, i.e. 37 thousand random shot radioactive discharges per second per kilogram (Bq/kg).
The December 2017 CLESA PCRSA based its assumptions on the 2006 amount: “The remaining ~70,000 m3 was assumed to be filled with waste corresponding to the original PCRSA fingerprint (i.e. 37 Bq/g, i.e. Table 1).” (CLESA PCRSA, 2017, p. 26). In the CLESA PCRSA they assume that “For future disposals the in-situ density was taken to be the same as the existing disposals, i.e. 2,030 kg/m3“. The current Environment Agency proposal states on p. 42 that “Units for liquid waste equivalent to LLW/ILW amended from GBq/m3 to GBq/t“. If adhered to, this means half the radiation for liquids. A GBq, Gigabecquerel, is a billion becquerels. A TBq, which appears in Sellafield documents, is a trillion becquerels. For regular pure water cubic meters (m3) is approximately one metric tonne.
Currently the amount that Sellafield (2018) gives for CLESA is 200 thousand Bq/kg – more than five times the original assumption used in the pre-opening impact study. The new proposed limit of 40 Million Bq/kg is more than one thousand times the assumption made for the 2006 impact study. If this includes radioactive materials other than tritium, then the proposed increase is even higher. According to CLESA PCRSA, 2017, Table 2, p. 19, approximately 23.4% is H3 (tritium). Thus the proposal may well be 200,000 Bq/kg of other radioactive materials plus 40,000,000 Bq/kg for tritium. This appears more likely the case, though it’s unclear. This tritium will remain radioactive for around 200 years. It is, of course, not the only radioactive material in this seaside and riverside landfill. The CLESA PCRSA Report (2017), based on Nexia (2006) and Halcrow (2006), notes that “in the absence of coastal defences, erosion of CLESA could begin in approximately 100 years’ time” (CLESA PCRSA, 2017, p.7) While the Environment Agency assume that someone will keep nature at bay for 200 years, there are other radioactive materials in this landfill, which remain radioactive far longer.
Note that for regular water, a kilogram is approximately one liter.
UK Environment Agency Aims to Increase Tritium Limit in Irish Seaside Landfill from 200 Thousand Bq/Kg to 40 Million Bq/Kg; Impact Studies (2006, 2017) Assume 37 Thousand Bq/Kg; A Bq is a Radioactive Shot Per Second: Comment Deadline Tonight
