Mutagenicity of radiations at low doses

RBE vs. dose for low doses of high-let radiations.

According to track theory, the relative biological effectiveness (RBE) of high linear energy transfer (LET) radiations varies with cellular radiosensitivity parameters and the radiation environment. Of special interest is that the RBE varies as the dose of high-LET radiation to the power (1/m - 1) where m is the "target number" parameter, which varies from 2-4 in different cell lines. This appl...

Quality factor for low doses of high-LET radiations.

Some reflections on the possible hazards to man of low doses of radiations.

that the dose received by the population in these regions has now risen to roughly twice the natural background level. External irradiation of the gonads by fallout is, in Europe and North America, very much smaller, probably I or 2% of the average dose distributed in the practice of diagnostic radiology. (2) There is the risk of leukaemia or bone cancer through the ingestion and deposition of ...

Potential treatment of inflammatory and proliferative diseases by ultra-low doses of ionizing radiations.

Ultra-low doses and dose- rates of ionizing radiation are effective in preventing disease which suggests that they also may be effective in treating disease. Limited experimental and anecdotal evidence indicates that low radiation doses from radon in mines and spas, thorium-bearing monazite sands and enhanced radioactive uranium ore obtained from a natural geological reactor may be useful in tr...

Biological Effects of Low Doses of Ionizing Radiations: Particle Tracks in Radiobiology

A radiation field is made up of a tangle of particle tracks, from the primary particle and secondary and higher generation electron interactions, well isolated at low doses and with multiple intersections in cell nuclei at high doses. Low dose effects in multicellular systems are therefore the sum of individual track structures. Until we can state with confidence the structure of a particle tra...
