Radiobiological Studies of Vaccinia Virus.
Radiation studies of vaccinia virus were carried out using two types of radiation, Coao gamma rays and ultraviolet light (UVL). When virus particles were irradiated with gamma rays a two-component survival curve was obtained. The capacity of Earle’s L cells to support the growth of vaccinia virus was relatively sensitive to gamma rays. Infectious centres formed by infecting L cells with vaccini...

متن کاملMonte Carlo studies on neutron interactions in radiobiological experiments
Monte Carlo method was used to study the characteristics of neutron interactions with cells underneath a water medium layer with varying thickness. The following results were obtained. (1) The fractions of neutron interaction with 1H, 12C, 14N and 16O nuclei in the cell layer were studied. The fraction with 1H increased with increasing medium thickness, while decreased for 12C, 14N and 16O nucl...
متن کاملMonte Carlo studies on photon interactions in radiobiological experiments
X-ray and γ-ray photons have been widely used for studying radiobiological effects of ionizing radiations. Photons are indirectly ionizing radiations so they need to set in motion electrons (which are a directly ionizing radiation) to perform the ionizations. When the photon dose decreases to below a certain limit, the number of electrons set in motion will become so small that not all cells in...
متن کاملAdvances in radiobiological studies using a microbeam.
Recent developments in microbeam technology have made drastic improvements in particle delivery, focusing, image processing and precision to allow for rapid advances in our knowledge in radiation biology. The unequivocal demonstration that targeted cytoplasmic irradiation results in mutations in the nuclei of hit cells and the presence of non-targeted effects, all made possible using a charged ...
