Edulis</i> L. from Ravenglass on the Esk estuary, Cumbria, UK which receives radioeffluents from the British Nuclear Fuels Ltd. (BNFL) plant at Sellafield, some 10 km to the north. Tidal position and mussel body size have a negigible influence on the concentration of <sup>241</sup>Am, <sup<137</sup>Cs and <sup>106</sup>Ru in the total soft tissue, but variation in soft tissue weight throughout the year has a considerable influence on the apparent concentration and depuration times of these radionuclides. Apart from the clearance (t<sub>1/2</sub> biol, 1 to 3 h) of sediment-associated activity from the digestive tract, the depuration rate profiles follow a single component clearance curve with a biological half-life in excess of 200 for <sup>241</sup>Am, <sup>239+240</sup>Pu, <sup>238</sup>Pu and <sup>144</sup>Ce, and of 40 d for <sup>137</sup>Cs. The clearance of <sup>106</sup>Ru is more complex and consists of a 3 component depuration profile with biological half-lives of 6 h, 12 d and 260 d. The depuration profiles presented in this work are for chronically ingested isotopes under natural conditions.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Concentration and depuration of some radionuclides present in a chronically exposed population of mussels (<i>Mytilus edulis</i>)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-30 01:31:10.713013","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1983,"MonPub":null,"DateUpdate":"2020-10-15","DateCreate":"2005-09-16","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1983QJ12100006","VABBcode":null,"OpenAcc":1,"DOI":"10.3354/meps011245"},"refs":null,"anarec":{"AnaID":76504,"PubliDate":1983,"Pagination":"245-256","XtraPublOfAnaID":null,"ISBN":null,"Volume":"11","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43354,"SerRR":"Marine Ecology Progress Series.
