Non-destructive Testing: Neutron Radiography

Neutron scattering techniques as a tool for non- destructive testing

Neutron scattering techniques, such as neutron diffraction, small angle neutron scattering and neutron reflectometry consist very powerful tools for the non-destructive study of materials. At the Greek Research Reactor, GRR-1, a number of neutron scattering methods are employed and developed. In the present contribution, a short description of the methods and facilities is given, as well as som...

Leaf area estimation by a simple and non-destructive method

In this study, the relation between leaf area and its dimensions was estimated using a non-destructive method. This method is based on this fact that the leaf shape does not change during the growing season. In this method, leaf area during the growing season is estimated based on the dimensions of the smallest leaf in the initial stage of plant growth or at any growth stage by measuring the le...

Monte Carlo Simulations for Non-destructive Elemental Analysis of Large Samples by Neutron Activation Analysis

Neutron Activation Analysis (NAA) is an established nuclear analytical technique with applications in a broad range of scientific and technological fields. Typically, conventional NAA involves analysis of small material portions of 10 to 100 g in mass. However, analysis of samples of a larger mass implies a number of additional advantages such as (a) analysis of objects too precious to remove ...

Non-destructive determination of maize leaf and canopy chlorophyll content.

The objective of this study was to develop a rapid non-destructive technique to estimate total chlorophyll (Chl) content in a maize canopy using Chl content in a single leaf. The approach was (1) to calibrate and validate a reflectance-based non-destructive technique to estimate leaf Chl in maize; (2) to quantify the relative contribution of each leaf Chl to the total Chl in the canopy; and (3)...
