Quantitative online isolation of (68)Ge from (68)Ge/(68)Ga generator eluates for purification and immediate quality control of breakthrough.
The breakthrough of (68)Ge from a (68)Ge/(68)Ga-generator is one of the most sensitive parameters in the context of the clinical application of (68)Ga-radiopharmaceuticals. The difficulty in its determination lies in the "spectroscopic invisibility" of (68)Ge within an excess of (68)Ga. The introduc...
Measurement of wavelength-dependent refractive indices of liquid scintillation cocktails.
Refractive indices of several commercial liquid scintillation cocktails were measured by means of an automatic critical-angle dispersion refractometer in the wavelength range from 404.7nm to 706.5nm. The results are needed for various applications. In particular, detailed Monte Carlo simulations of...
Separation technique for the determination of ⁹⁹Tc in milk and dairy products in case of emergency.
A method for the determination of (99)Tc (T1/2: 2.1 × 10(5)a) in milk and dairy products is presented in detail. The method includes the separation of fat and proteins from milk, the separation of Tc by anion exchange from other metals and the purification of Tc by extraction chromatography with sub...
Design of an electrochemically assisted radiation sensor for α-spectrometry of actinides traces in water.
We describe a new approach for the detection and identification of actinides at low activity levels directly in aqueous solution. The measurement consists initially, in immobilizing alpha emitters in the form of insoluble hydroxides onto the entrance window of an immersed alpha particles detector. F...
Implementation of gamma-ray spectrometry in two real-time water monitors using NaI(Tl) scintillation detectors.
In this study, the implementation of gamma-ray spectrometry in two real-time water monitors using 2in.×2in. NaI(Tl) scintillation detectors is described. These monitors collect the water from the river through a pump and it is analyzed in a vessel, which is shielded with Pb. The full calibration of...
Investigation of activation cross-section data of proton induced nuclear reactions on rhenium.
In the frame of systematic investigations of activation cross-section data for different applications the excitation functions of (nat)Re(p,x)(185)Os, (183m)Os, (183g)Os, (182)Os, (181m)Os, (186g)Re, (184m)Re, (184g)Re, (183)Re, (182m)Re, (182g)Re and (181g)Re reactions were measured up to 70MeV. Th...
Characterization of a 6Li-loaded liquid organic scintillator for fast neutron spectrometry and thermal neutron detection.
The characterization of a liquid scintillator incorporating an aqueous solution of enriched lithium chloride to produce a scintillator with 0.40% (6)Li is presented, including the performance of the scintillator in terms of its optical properties and neutron response. The scintillator was incorporat...
Boron neutron capture therapy and (18)F-labelled borophenylalanine positron emission tomography: A critical and clinical overview of thelite...
Positron emission tomography (PET) is considered one of the most useful tool for molecular imaging both in clinical and preclinical research for in vivo assessing of biochemical and pharmacological processes. Boron neutron capture therapy (BNCT) is a biologically-targeted radiotherapy that can selec...
In vivo molecular imaging of [125I]-labeled 3-iodothyronamine: a hibernation-inducing agent.
The present investigation was carried out with the objective of studying in vivo imaging of 3-iodothyronamine (T(1)AM) compound in mice. A simple and efficient synthesis of [(125)I]-T(1)AM was established, and a molecular imaging study was performed using micro-SPECT/CT at 1h post-injection of [(125...
Suppression of β-particle events using a capillary tube in liquid scintillation α spectrometry.
A method to decrease photons generated by β particles by using a capillary tube in liquid scintillation α spectrometry is presented. Liquid scintillation counting of (241)Am and (152)Eu was performed with 200, 300, and 500μm inner diameter (i.d.) PFA tubes as the detection cell. It was observed that...
