1. Cellular effects of ionizing radiation : Relevant for understanding cancer risk after medical and environmental radiation exposures
Abstract : Radiation-induced cancers are stochastic and delayed effects of exposure to ionizing radiation. The dose-response relationship for radiation-induced cancers at both low dose/low dose rates and high doses (doses encountered during radiotherapy) remains unclear. READ MORE

2. Consequences of Poor Housing : Essays on Urban and Health Economics
Abstract : Essay I: Research shows that low fetal doses of radiation from nuclear catastrophes and atmospheric test bombings of nuclear weapons cause cognitive birth defects. These events are uncommon and the radioactive isotopes they create rarely reach harmful levels in nature. READ MORE

3. Internal Dosimetry in Nuclear Fuel Fabrication : Occupational Exposure to Uranium Aerosols
Abstract : The production of nuclear fuel can be associated with occupational exposure to ionizing radiation from radioactive decay of uranium. Such exposure must be sufficiently low and radiation doses adequately determined. Radiation doses from internal exposure, i.e. READ MORE

4. Role of MTH1 and MYH proteins in genotoxic effects of radiation
Abstract : Humans are constantly exposed to different types of radiations. It has been suggested that low dose and low dose rate of γ-radiation as well as ultra violet A (UVA) induce oxidative stress in cells that may promote mutations. READ MORE

5. Biomarkers of ionising radiation relevant to carcinogenesis : Dose, dose rate and LET dependency of the responses
Abstract : A better understanding of the relationship between ionising radiation (IR) dose, dose rate and radiation quality, and the risk of stochastic effects would improve risk extrapolation from atomic bomb survivors’ data. Owing to insufficient statistical power of epidemiological studies to detect excess incidence of cancer following low doses of IR delivered at low dose rates (LDLDR), as typically encountered in most common human exposure scenarios, radiobiological experiments are fundamental to describe the biological effectiveness of LDLDR and to define the underlying molecular mechanisms.
