Zusammenfassung:
This dataset describes the results of an interlaboratory comparison exercise, focusing on comparing the capabilities of different mass spectrometers for low-level radioactivity measurement. Participating labs around Europe were asked to determine activity levels for a range of actinides (²³⁴U, ²³⁶U, ²³⁷Np, ²³⁹Pu, ²⁴⁰Pu, ²⁴¹Am, NatU and ²³⁹/²⁴⁰Pu) and ⁹⁰Sr. Standards were prepared from starting materials at NPL through a series of dilutions using a dedicated source preparation facility and characterised for their activity per unit mass and impurities using a combination of decay counting and mass spectrometric techniques. Standards were distributed to participating laboratories along with a form for submitting the results and details of the measurements made. There were delays in sending of the materials to the participating laboratories, however, results were submitted for all radionuclides using multiple techniques. This provides valuable information on the capabilities of mass spectrometry for low-level radionuclide measurement and can inform the development of future standards and comparison exercises.

Description of the individual files:* Table06 = Assigned values for radionuclide standards used in the comparison exercise. * Table07 = Values for radionuclides used in isotopic ratio standards for the comparison exercise. * Table09 = Table of results and performance for ⁹⁰Sr standard. * Table10 = Table of results and performance for ²³⁴U standard. * Table11 = Table of results and performance for ²³⁶U standard. * Table12 = Table of results and performance for ²³⁷Np standard. * Table13 = Table of results and performance for ²³⁹Pu standard. * Table14 = Table of results and performance for ²⁴⁰Pu standard. * Table15 = Table of results and performance for ²⁴¹Am standard. * Table16 = Table of results for uranium mixed standard. * Table17 = Table of results and performance for Plutonium mix standard. Common information: * Research object = Single and mixed radionuclide standard solutions. * Method = Decay counting and mass spectrometric techniques. * Format = XLSX, TSV (tab separated) * Recommended software = Excel, LibreOffice, OnlyOffice * Variables = + Activity in Bq/g + Isotope Ratios in mol/mol + DoE (Degree of Equivalence) = difference between the measured value xi and the reference value xref. + E_n = ratio of the DoE to the own uncertainty u(DoE) = √[u²(xi )+u²(xref)] . E_n < 1 means a good correspondence of the measurement result with the reference value. |

Bemerkung:
The information in this dataset is associated with the Deliverable "D1: Inter-laboratory comparison report for low-level radionuclide detection by mass spectrometry", showing the same data but in a more user friendly format than the pdf-format of the Deliverables, following the FAIR data principles. The Deliverable report should be consulted to receive more information about the determination of the data within the dataset:The Deliverable report is published in the PTB-OAR: https://doi.org/10.7795/120.20251017C. |
