Radioisotopes applications in industry: an overview
Radioactive isotopes, particularly in the form of radiotracers and radioactive sealed sources, have been used over a broad spectrum of process industries for equipment and process troubleshooting, monitoring, control, inspection, optimisation and many other purposes. Radioisotope-based measurement techniques are best suited for multiphase flow systems encountered in industrial processes, since ...

Stable Isotope Analysis Techniques: Powerful Analytical Tools for Various Fields
What Are Stable Isotope Techniques? A class of atoms with the same number of protons but different numbers of neutrons in the nucleus is called isotopes, which can be divided into stable isotopes and radioactive isotopes. The nucleus of a radioactive isotope is unstable, and it decays into another isotope by spontaneously emitting particles. Isotopes that are not radioactive are called stable ...

Air Sampling During NPP Accident
There has been considerable interest recently generated regarding emergency air sampling protocols as a result of the Fukushima accident in Japan. A major concern involving air sampling requirements is the accurate determination of gaseous-radioactive iodine species emitted from the NPP to the environment as a result of an accident. During normal NPP operation gaseous radioactive iodine ...

Prediction of solid‐solution partitioning coefficients (Kd) for cationic metals in soils using mid‐infrared diffuse reflectance spectroscopy
Partial least squares regression (PLSR) models, using mid‐infrared (MIR) diffuse reflectance Fourier transformed (DRIFT) spectra, were used to predict distribution coefficient (Kd) values for selected added soluble metal cations (Ag+, Co2+, Cu2+, Mn2+, Ni2+, Pb2+, Sn4+, and Zn2+) in 4813 soils of the Geochemical Mapping of Agricultural Soils (GEMAS) program. For the development of the PLSR ...

Prj 9121 - Deactivation of radioactive water - Case Study
Although radioactive isotopes are engaged for many applications (i.e. medicine, metallurgy, etc.), the major sources of soil and water contamination with radioactive substances are connected to nuclear waste processing and to uranium mining operations. One of the principal carcinogens is plutonium and any soil or water contaminated by plutonium should be carefully removed and disposed in ...

A study on the distribution coefficient of bromide ions from aqueous solution on ion exchange resins Duolite A-101D and Duolite A-102D
The ion exchange resins Duolite A-101D and Duolite A-102D in bromide form were equilibrated separately with labelled radioactive bromide ion solutions of different concentrations varying from 0.005 M to 0.100 M in the temperature range of 25.0°C to 45.0°C. The Kd values of bromide ions for Duolite A-102D were higher than that for Duolite A-101D under identical experimental conditions. The ...

How to Treat Hospital Wastewater by Electrocoagulation
In this article, we will discuss the sources of hospital wastewater, the effects of hospital wastewater on the environment, and how innovative electrocoagulation treatment technology can be sustainably used as part of an integrated hospital wastewater treatment system to effectively treat this contaminated wastewater stream. When people are sick or injured, they typically go to a hospital to ...

Non–destructive radiotracer technique in characterisation of nuclear grade anion exchange resins Tulsion A–30 and Dowex 550A LC
The present study deals with the application of non–destructive radio isotopic tracer technique to evaluate the performance of nuclear grade resins Tulsion A–30 and Dowex 550A LC. The evaluation was made by testing the performance of the two resins during iodide and bromide ion–isotopic exchange reactions. It was observed that at a constant temperature of 30°C, as the concentration of labelled ...

An overview of recent IAEA projects on mercury in non-marine environments
Nuclear and isotopic techniques are unique tools for studying mercury contamination and cycling in various environments. Therefore, the International Atomic Energy Agency (IAEA) has been supporting the use of nuclear and complementary analytical techniques (mainly neutron activation analysis, inductively coupled plasma – mass spectrometry and atomic absorption spectrometry), and application of ...

Radon Air Stripping of Well Water
Radon is Frequently Found in Ground Water Radon, symbol Rn, atomic number 86, is a colorless, odorless gas at ambient conditions. It is the heaviest element of the Noble Gas family. As such it is extremely stable and unreactive chemically. But it also is highly radioactive. Its half-life is only 3.8 days. Both Thorium, symbol Th, atomic number 90 and Uranium, symbol U, atomic number 92, have no ...

Better tools for fast and convenient Patulin analysis
Analytical Standards and New SupelMIP SPE Cartridges The mycotoxin patulin is often found in rotten apples. It is mostly produced by Aspergillus, Penicillium and Byssochlamys and shows a variety of short-term and long-term effects in animal studies, ranging from gastrointestinal problems and neurotoxicity to genotoxicity and teratogenicity. Therefore, many countries set limits for patulin ...
