title: Determination of 210Po in marine organism by pressure tank digestion and Alpha spectrometry
title: 压力罐消解-α能谱法测定海洋生物中的210Po

description:  [Background] 210Po in seafood is the main source of the total internal irradiation dose received by the population, and it is particularly important to accurately determine the activity concentration of 210Po in marine organisms. [Purpose] This study aims to develop a method for the determination of 210Po in marine organism by pressure tank digestion and Alpha spectrometry. [Methods] Sample, with the addition of a 209Po yield tracer, was digested by pressure tank method. 210Po was then spontaneously plated onto nickel disk in hydrochloric acid system and measured with α spectrometer. The experimental conditions were optimized for both digestion (acid selection, acid dosage, temperature, duration) and auto-deposition (temperature, time, HCl concentration, solution volume, types of metallic discs). The proposed method was validated by the analysis of a certified reference material IAEA-414. [Results] With the optimized conditions, the measurement results of 210Po in fish sample IAEA-414 fall within the confidence interval of 1.55～2.60 Bq·kg-1. The relative standard deviation is 9.0%. The recovery rates of 209Po tracer for reference samples vary from 92.9% to 98.6%. The detection limit of the method is 0.18 Bq·kg-1. [Conclusions] This method is simple, rapid and accurate, and can be applied to measurement of 210Po in marine organism.

title: Beach profile data for the Elwha River Delta, 2022-11-21

description: Shoreline topography data were collected using GNSS survey methods, with a differential GPS, typically an AshTech ProMark 200 RTK-DGPS system connected to the Washington State Reference Network, operating in Real Time Kinematic (RTK) mode. Survey data are referenced in the horizontal reference frame to NAD83(2011). Elevations, in meters, are referenced to NAVD88(Geoid09) for all survey data collected before December 2012, NAVD88(Geoid12) for all survey data collected between December 2012 and May 2020, and NAVD88(Geoid18) for all survey data collected subsequently. No conversions were applied to these data to account for variations in horizontal or vertical coordinate system adjustments through time, but an error analysis suggests a standard deviation for the elevations of between 0.03 and 0.05 m across the entire sampling period (2011-2024). All survey data were collected with the GNSS system mounted on a 2.05 m rover pole, held level by a surveyor as a transect line was traced in a cross-shore orientation on the beach. The associated text files include the horizontal (HRMS) and vertical (VRMS) root-mean-square errors estimated by the GNSS system, as well as the RTK-DGPS status reported by the GNSS system at the time each point was collected. Times are referenced to local Pacific time (either PST or PDT).
