{"doi":"10.1093/rpd/ncaa180","title":"DETERMINATION OF 226RA IN URINE USING TRIPLE QUADRUPOLE INDUCTIVELY COUPLED PLASMA MASS SPECTROMETRY","abstract":"Measuring 226Ra in urine at low levels is critical for both biomonitoring and radiological emergency response. Here we report a new analytical method to quantify 226Ra, as developed and validated by a simple dilute-and-shoot procedure, followed by Inductively Coupled Plasma-triple quadrupole-mass spectrometry detection using 'No Gas MS-MS' mode. The method provides rapid and accurate results for 226Ra with a limit of detection (LOD) down to 0.007 ng/l (0.26 Bq/l). This LOD is well below the recommended action levels for 226Ra detection in children and pregnant women (C/P) set by the Clinical Decision Guide (NCRP Report #161). Results for 226Ra obtained by this method are within ±7.0% of the target values of standard reference materials spiked in the urine.","journal":"Radiation Protection Dosimetry","year":2020,"id":106826,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":7,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9535,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2020-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":514775,"name":"Yongzhong Liu","orcid":"0000-0001-6624-7549","position":1,"is_corresponding":false},{"id":296626,"name":"Robert L.
