These recommendations are a vocabulary of basic radioanalytical terms which are relevant to radioanalysis, nuclear analysis and related techniques. Radioanalytical methods consider all nuclear-related techniques for the characterization of materials where 'characterization' refer ...
As a safer alternative for the use of radioactive tracers, the enriched stable 58Fe isotope has been introduced in studies of iron metabolism. In this study this isotope is measured with instrumental neutron activation analysis (INAA) in blood samples of patients with iron relate ...
The neutron irradiation of molybdenum hexacarbonyl has been systematically studied to identify possible improvements for the production of molybdenum-99. After
irradiation, the targets were dissolved in dichloromethane, and Szilard-Chalmers liquid-liquid extraction was carrie ...
Accurate assessments of the iron (Fe) intake from food is mandatory for mass balance studies. The reliability of such assessments is strongly dependent on the representativeness of the analytical test portion and, as such, the quality of the homogenization of the double portions ...
Iron deficiency anaemia is a major health problem worldwide, but may be complicated in underdeveloped nations by deficiencies of other micronutrients with consequences for adequate treatment. The World Health Organization (WHO) estimates that 2 billion people – over 30% of the wo ...
A crucial part of any chemical analysis is the degree of representativeness of the measurand(s) in the test portion for the same measurands in the object, originally collected for investigation. Such an object usually may have either to be homogenized and sub-sampled, or digested ...
This study examines the potential to use instrumental neutron activation analysis (INAA) to explore temporal and geographical variation in exposure to heavy metals and other selected elements in common kestrel Falco tinnunculus using feathers from a natural history collection. Th ...
The quality of dog diets depends on adequate ingredients capable of providing optimal nutrition and free of contaminants, for promoting long-term health. Trace elements in 95 samples of dry food for dog puppies (n = 32) and adults (n = 63) of various brands were measured using in ...

Determination of 54 elements in lichen transplants

Comparison of INAA, ICPMS, and EDXRF

Three multi-element techniques employed for analysis of lichen transplants deployed at sites in Romania with strongly differing exposure to air pollutants were compared with respect to precision and determination limits for 54 elements. The results obtained for Evernia prunastri ...
