The high level natural radiation areas (HLNRA) of Kerala coast in south west India is unique for its wide variation in the background radiation dose (<1.0mGy to 45mGy/year) and vast population size. Several biological studies conducted in this area did not reveal any adverse effects of chronic low dose and low dose rate radiation on human population. In the present study, global transcriptome a...

This article discusses the natural history, clinical epidemiology, diagnosis, and treatment of radiation-induced lung diseases (RILDs). Furthermore, we review current experimental developments and assess potential areas for future investigation. Radiation therapy (RT) is a key component of the approach to the treatment of thoracic neoplasms. The use of radiation for the treatment of cancer expl...

Cancer causing potential of chronic exposure to high natural radiation seen in Chavara– Neendakara coast of Karunagappally taluk in Kerala, India is studied by the Natural Background Radiation Cancer Registry, Karunagappally since 1990. Population survey of 359,619 people recorded socio-demographic (SD) information and radiation levels measured inside (71,674) and outside (76,942) houses. Radia...

using natural gas as a clean, plentiful and inexpensive source of energy in recent years has progressively increased in iran. pipelines are the most common system to transport natural gas from field to different regions of iran. these pipelines always pose risks to surrounding population and environments. the aim of this study was to assess the potential health, safety, and environment risk of ...

BACKGROUND Telomere length is considered as a biomarker of aging, stress, cancer. It has been associated with many chronic diseases such as hypertension and diabetes. Although, telomere shortening due to ionizing radiation has been reported in vitro, no in vivo data is available on natural background radiation and its effect on telomere length. METHODOLOGY/PRINCIPAL FINDINGS The present inves...

It is proposed that vitamin D is a protective factor against colon cancer. This hypothesis arose from inspection of the geographic distribution of colon cancer deaths in the U.S., which revealed that colon cancer mortality rates were highest in places where populations were exposed to the least amounts of natural light--major cities, and rural areas in high latitudes. The hypothesis is supporte...

background: natural radionuclides are always present in the environment. human exposure to the background radiation is inevitable. it is therefore important to assess health risk associated with these radionuclides. materials and methods: the distribution of natural radionuclides 238u, 232th and 40k in soil samples collected from all the twenty (20) local governments headquarter areas in ogun s...

  Ionizing radiation has long been known to produce detrimental biological effects. Although these harmful effects are the results of high doses of exposure, some other maladies such as mutation and cancer seems  to be induced at low doses of exposure. In recent decades, however, some pioneer scientists have indicated that ionizing radiation like many other essential agents has toxic effects  ...

natural climatic conditions in urban areas can be changed by human physical environment. climate as a natural system and city as a human system have close mutual connections. urban population growth and consequent increase in urban physical expansion may lead to intensification in human activities and disturbances in the environment. this contributes to alterations in solar radiation, balance o...
