A calibration method for realistic neutron dosimetry in radiobiological experiments assisted by MCNP simulation
Many studies on biological effects of neutrons involve dose responses of neutrons, which rely on accurately determined absorbed doses in the irradiated cells or living organisms. Absorbed doses are difficult to measure, and are commonly surrogated with doses measured using separate detectors. The present work describes the determination of doses absorbed in the cell layer underneath a medium co...
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 کاملImprovement of Accuracy in Environmental Dosimetry by TLD Cards Using Three-dimensional Calibration Method
Background: The angular dependency of response for TLD cards may cause deviation from its true value on the results of environmental dosimetry, since TLDs may be exposed to radiation at different angles of incidence from the surrounding area.Objective: A 3D setting of TLD cards has been calibrated isotropically in a standard radiation field to evaluate the improvement of the accuracy of meas...
متن کاملA Graphical User Interface For Diagnostic Radiology Dosimetry Using Monte Carlo (MCNP) Simulation
INTRODUCTION Monte Carlo (MC) methods have become the "gold standard" for assessing dose distribution, organ doses and effective dose associated with the exposure, both external and internal, of humans to ionizing radiation. Powerful and sophisticated tools for simulation of radiation transport (for example, MCNP, EGS4) are now widely available. However, these codes are designed for general-pur...
متن کامل131i-chlorotoxin dosimetry in liver using mcnp simulation code
chlorotoxin is a 36 amino acids peptide, which is able to block chloride channels isolated from mouse brain. a derivative of chlorotoxin is synthesized and it is labeled by iodine 131; then animal experiments carry out on rats. multiple organ doses may be calculated with biological distribution results in rats with labeled compounds using simulated mcnp4c code. human dose can be calculated usin...
