The k0 method is a highly successful standardization method developed for Neutron Activation Analysis (NAA), later also introduced in Prompt Gamma Activation Analysis (PGAA). After the careful calibration of the irradiation and counting facilities, the k0 method makes the use of elemental standards unnecessary. Masses of the components are determined relative to the flux monitor, or, in the case of PGAA, to other known components of the sample. The development of the method is summarized in this review together with the description of methods implemented at different laboratories. The activities carried out in the laboratories of the authors are described as examples for the successful implementation of the k0 approach to activation analysis.

“…Those methods provide reliable results for the composition of the whole coin and, moreover, are non‐destructive. The disadvantage of these methods is the high cost of measurement and the determination of only the actual fineness (Beck et al , ; Kasztovszky et al ).…”

Determination of the Fineness of Medieval Coins—Evaluation of Methods in a Case Study of a Medieval Pfennig

The original fineness of coins is very important information that can help us to understand the commercial situation in a wide historical context. This paper deals with a comparison of analytical methods suitable for the evaluation of the actual and original fineness of coins based on a detailed case study of a medieval coin sample. Both non-destructive (i.e., scanning electron microscopy/energy-dispersive X-ray spectroscopy, X-ray fluorescence, atomic force microscopy and hydrostatic weighing) and destructive (i.e., inductively coupled plasmamass spectrometry and the Volhard titration method) techniques were used. The original fineness can be also deduced from knowledge of the internal structure of the coin (limited miscibility of copper and silver). A new analytical method based on a combination of a micrograph of the metallographic cross-section with consequent image analysis was developed for determination of the original fineness. The proposed approach is relatively simple and provides reliable values. Sample heterogeneity and its impact on the determination of fineness are also discussed.

The Use of Neutron Analysis Techniques for Detecting The Concentration And Distribution of Chloride Ions in Archaeological Iron

et al. 2013

Chloride (Cl) ions diffuse into iron objects during burial and drive corrosion after excavation. Located under corrosion layers, Cl is inaccessible to many analytical techniques. Neutron analysis offers non-destructive avenues for determining Cl content and distribution in objects. A pilot study used prompt gamma activation analysis (PGAA) and prompt gamma activation imaging (PGAI) to analyse the bulk concentration and longitudinal distribution of Cl in archaeological iron objects. This correlated with the object corrosion rate measured by oxygen consumption, and compared well with Cl measurement using a specific ion meter. High-Cl areas were linked with visible damage to the corrosion layers and attack of the iron core. Neutron techniques have significant advantages in the analysis of archaeological metals, including penetration depth and low detection limits.
