AbstractAbstract
[en] In the use of nuclear techniques, one of the safety problems is the protection of personnel and delicate instruments against harmful radiation. It is therefore of prime importance that the designer of nuclear experiments have a basic understanding of how radiation behaves when it passes through matter. This is a tutorial paper that presents the fundamentals of electromagnetic radiation with respect to its interaction and absorption in matter. (author)

AbstractAbstract
[en] An approach to resolving some problems in nuclear geophysics which relate to heterogeneous media is presented. The theory is based on an effective parameters method, which enables a single scheme to be used for solving problems involving γ-ray and neutron sources. This paper is the first of two and deals specifically with the basic theory and γ-ray transport problems. (Author)

AbstractAbstract
[en] SGRD (Spectroscopy, Gamma rays, Rapid Deterministic) code is used to infer the dimensions of a one-dimensional model of a shielded gamma ray source. The method is based on the simulation of the un-collided leakage current of discrete gamma lines that are produced by nuclear decay. Experimentally, the unscattered gamma lines leakage current is obtained by processing high precision gamma spectroscopy measurements. The material thicknesses are computed with SGRD using a fast ray-tracing algorithm embedded in a non-linear multidimensional iterative optimization procedure that minimizes the error metric between calculated and measured signatures. For verification, numerical results on a test problem are presented. The test problem is a spherical natural shell surrounded by polyethylene (CH2) and an aluminium cover. The gamma source is due to uranium radioactive decay and 5 characteristic lines are chosen for the optimization. The comparison between the initial and the optimized gamma line spectra with measurement simulated by direct transport calculation shows that the optimization method works well
