A new method for tooth (enamel and dentine) and bone EPR dosimetry is proposed that enhances substantially the dosimetric sensitivity. The method is based on the nonstandard spectra registration mode (the second harmonic phase quadrature detection of absorption under rapid passage conditions). This method provides an apparent enhancement of the component ratio of radiation to a nonradiative bac...

conclusion we constructed and validated a ct colonography phantom with correct density allowing performance of reproducible experiments. materials and methods we found 15 different phantom designs by literature search and compared their advantages and disadvantages based on their description and images. we tested various materials for density and mechanical properties and constructed a phantom ...

the adaptive response (ar) is a phenomenon by which cells exposure to sublethal doses of dna-damaging agents (non-mutagenic dose of chemical or radiation), known as conditioning treatment (ct), leads to increased resistance to a subsequent exposure to a higher dose of the same or other agents, known as challenge treatment (cr). the adaptive response (ar) induced by radiation in human lymphocyte...
