Species sensitivity of zeolite minerals for uptake of mercury solutes [PDF]

, 2006
The uptake of inorganic Hg2+ and organometallic CH3Hg+ from aqueous solutions by 11 different natural zeolites has been investigated using a batch distribution coefficient (Kd) method and supported by a preliminary voltammetric study.

Technical note: Comparison of radiometric techniques for estimating recent organic carbon sequestration rates in inland wetland soils [PDF]

Biogeosciences
For wetlands to serve as natural climate solutions, accurate estimates of organic carbon (OC) sequestration rates in wetland sediments are needed. Dating using cesium-137 (137Cs) and lead-210 (210Pb) radioisotopes is commonly used for measuring OC ...

New developments in the experimental data for charged particle production of medical radioisotopes [PDF]

, 2015
The goal of the present work is to give a review of developments achieved experimentally in the field of nuclear data for medically important radioisotopes in the last three years. The availability and precision of production related nuclear data is continuously improved mainly experimentally. This review emphasizes a couple of larger fields: the Mo/Tc
