Quantitative autoradiography in boron neutron capture therapy considering the particle ranges in the samples

Physica Medica, 2021
Boron neutron capture therapy is a cellular-scale particle therapy exploiting boron neutron capture reactions in boron compounds distributed in tumour cells. Its therapeutic effect depends on both the accumulation of boron in tumour cells and the neutron fluence.

Nonphotographic Alpha Autoradiography and Neutron-Induced Autoradiography

Science, 1970
With a new combination of two techniques, (i) alpha-particle or fission fragment registration in thin polymer foils by etching and (ii) automatic counting and magnification of the etched perforations by local evaporation of a thin metal layer with an electric spark, the sensitivity of conventional photographic methods for determining quantity and ...

Neutron Autoradiography of Trace Amounts of Gadolinium

Nuclear Technology, 1992
This paper reports that application of gadolinium in neutron capture therapy is under evaluation. Crucial to development of this therapy is an imaging technique that would show the distribution and concentration of parts-per-million amounts of {sup 157}Gd in sliced samples.

Autoradiography of neutron-activated rock slabs

Chemical Geology, 1970
Abstract Autoradiographs in macro-scale of rocks are produced after subjecting polished rock slabs to thermal neutron activation. The obtained picture shows the distribution of induced activity in the rock slab. 1–5 days after irradiation most of the exposure of the film is due to 24 Na formed by ( n , γ) reaction from natural sodium ( 23 Na). After

Neutron-induced autoradiography of lithium silicate glasses

Journal of Materials Science, 1970
Immiscibilities between silica and lithium disilicate were investigated. Alpha particles ejected from 6Li atoms by thermal neutrons were used to autoradiograph surfaces representing diffusion-zone cross-sections. Etchant-enlarged alpha tracks in nitrocellulose disclosed the distribution of lithium.

Neutron Activation Autoradiography

2016
Autoradiography uses a photographic film or imaging plate which are placed in direct contact with a painting after irradiation by slow neutrons. The pigments become radioactive after the interaction with the neutron beam and the emitted radiation (gammas, X-rays and electrons, so called beta-rays) is registered in the film or plate.

Nitrogen distribution measurements by neutron induced autoradiography

Journal of Radioanalytical and Nuclear Chemistry, 1998
A method utilizing plastic track detectors was developed to determine the nitrogen distribution and concentration in the presence of boron in metals. Experiments were performed at the UVAR (cadmium ratio ≈25) and the NIST Reactor (cadmium ratio ≈3000). The minimum detectable concentration of nitrogen at a given concentration of boron has been estimated

A Technique of Neutron-Induced (Fission-Track) Autoradiography with Histological Detail

Radiation Research, 1980
The primary advantage of neutron-induced or fission-track autoradiography compared with conventional autoradiography is that for low concentrations of fissile nuclides prohibitively long exposure times may be avoided. However, it is difficult to produce imaging of biological structures on the neutron-induced autoradiograph which would allow ...
