The NanoSIMS ion probe is a new-generation SIMS instrument, characterised by superior spatial resolution, high sensitivity and multi-collection capability. Isotope studies of certain elements can be conducted with 50–100 nm resolution, making the NanoSIMS an indispensable tool in many research fields. We review technical aspects of the NanoSIMS ion probe and present examples of applications in ...

A new region of proton-rich parent nuclei decaying by spontaneous cluster emission with a measurable branching ratio relative to alpha decay is predicted within the analytical superasymmetric fission model. After a brief presentation of the model and of the seven mass tables used to calculate the released energy, the obtained results are discussed. Measurable half-lives and branching ratios are...

Abstract Contamination of aquatic ecosystems with radioactive nuclides is significantly threaten the human body. So, finding effective and economical sorbents significant for uranium elimination from an aqueous solution important. In this study, Cement kiln dust (CKD) a solid waste produced during cement production process was utilized as sorbent sorption solution. The maximum adsorption 156.2 ...

We present a Bayesian approach to probabilistically infer vertical activity profiles within radioactive waste drum from segmented gamma scanning (SGS) measurements. Our resorts Markov chain Monte Carlo (MCMC) sampling using the state-of-the-art Hamiltonian (HMC) technique and accounts for two important sources of uncertainty: measurement uncertainty in source distribution drum. In addition, our...

For appropriate safety assessment of the disposal of TRU waste, distribution coefficients (Kd) and gasification ratios of C labeled [1, 2-C] sodium acetate (C-NaOAc) were determed by batch sorption tests for 85 Japanese paddy soil samples. The soil studied were from four soil types: Andsol; Gley; Gray lowland; and Yellow. The range of Kd values for all soil samples was from 7.5 to 295.2 mL g , ...

Portal monitors and mobile search systems are most effective in positive identification when constructed with high resolution detectors. To satisfy the need for this type of detector, an integrated gamma ray spectrometer, incorporating a germanium detector with integral mechanical cooling, digital signal processing electronics, MCA, and communications has been developed. This modular subsystem ...
