Comparative Mutagenic Action of X-rays and Cyclotron Neutrons on Dormant Seeds of Rice

Cytogenetic Effects of X-Rays and Thermal Neutrons on Dormant Tomato Seeds.

HE study reported in this paper concerns the effects of X-rays and thermal neuT trons on dormant seeds of the tomato, Lycopersicon esculentum, expressed as chromosomal abnormalities in root tip mitoses, seedling injury, and chlorophyll and morphological changes. XI and NI refer to the X-rayand thermal neutron-irradiated generations, respectively; Xz and Nz to the progenies of the XI and NI gene...

Comparison of Effects of X-Rays and Thermal Neutrons on Dormant Seeds of Barley, Maize, Mustard, and Safflower.

On the reflectivity of polymers: Neutrons and X-rays

Over the last few years reflectivity methods have emerged as key tools for the investigation of polymer surfaces and interfaces. The high spatial resolution of these techniques, of the order of 5 A, has provided a means of probing density gradients in polymers on a submolecular level. This resolution, coupled with selective labeling of all or parts of polymer chains has permitted the examinatio...

The Comparative Effects of Neutrons and X-rays on the Whole Body

Irradiation of the whole bodies of mice with neutron rays in sufficient quantities, leads to a clinical, bacteriological and anatomical picture similar to that following Roentgen irradiation. The mucosa of the small intestine and the lymphoid and hemapoietic tissues are the most radiosensitive. The mechanism of death after both forms of radiation seems to be a combination of tissue destruction ...

Bimodal Imaging Using Neutrons and X-rays

Experiments that combines the information from two different radiation sources can provide more information than experiments using single radiation sources. This claim was confirmed using the bimodal installation at the thermal neutron imaging beamline NEUTRA at Paul Scherrer Institut. This installation is equipped with a 60-320kV X-ray source and is used for mid-sized samples. The combination ...
