Neutron Activation Autoradiography as a Technique for Conservation Examination of Paintings

Bulletin of the American Institute for Conservation, 1975
Conservators of oil paintings are properly concerned with the in depth structures of the paintings they are to treat. A thorough knowledge of the nature and extent of alterations that have occurred within the paintings either through changes made by the original artist, through previous conservation treatment or through deterioration is essential for ...

Neutron Radiography and Autoradiography at the J. Stefan Institute

1983
At 250 kW TRIGA MARK II Reactor in Ljubljana two different neutron radiographic facilities are constructed. One facility is primarily used for NR inspection of macroscopic objects, while the other is intended for microneutronography and neutron induced autoradiography.

Neutron autoradiography imaging of selective boron uptake in human metastatic tumours

Applied Radiation and Isotopes, 2008
The ability to selectively hit the tumour cells is an essential characteristic of an anti-tumour therapy. In boron neutron capture therapy (BNCT) this characteristic is based on the selective uptake of (10)B in the tumour cells with respect to normal tissues.

The visualisation of fissionable radionuclides in rat lung using neutron induced autoradiography

Physics in Medicine & Biology, 1978
The development of a technique in which images of soft tissue sections are produced in Lexan by irradiating with alpha -particles is reported. This technique has been used, together with neutron induced autoradiography, to visualise the distribution of 235UO2 in sections of rat lung.

An Examination of Neutron Induced Autoradiography and Gamma Spectroscopy for the Study of Paintings

MRS Proceedings, 1988
Neutron-induced autoradiography is a further step in the development of techniques for the examination of paintings that complements x-ray radiography and often yields unique information that cannot be obtained by other means. After exposure to a field of thermal neutrons (<0.3eV), selected elements in the painting form radioactive nuclides that in ...

Neutron induced autoradiography of some minerals from the allchar mine

Radiation Measurements, 1999
Abstract The mineral lorandite from the Allchar mine (Kavadarci, Macedonia) will be used to estimate the average solar neutrino flux. Here, the amount of 205 Pb isotope induced by the 205 Tl(ν e ,e − ) 205 Pb reaction is measured and converted to neutrino flux. To determine the few 205 Pb atoms that are produced by solar neutrinos in the Tl ore it

Comparison of Neutron Induced Autoradiography by Means of a Neutron Source ²³²Cf and by a Reactor

Isotopenpraxis Isotopes in Environmental and Health Studies, 1987
For study of distribution of several elements (mainly boron) in the brazed joints of Ni-base alloys and for optimization of post-bond heat treatment of the joints the neutron induced autoradiography (NIAR) using solid state nuclear track detectors (SSNTD) has been applied. For a big isotopic neutron source 252Cf a special hexagonal tank was constructed,

Distribution of Sodium in Compact Bone, as Revealed by Autoradiography of Neutron-Activated Sections

Nature, 1959
RECENT work has emphasized the heterogeneous composition of compact bone. According to X-ray absorption, young osteons contain less calcium than the others1. Histological methods indicate that the mucopolysaccharides of the ground-substance are different in the preosseous layers, in the incompletely calcified osteons, and in the fully mineralized ...
