  • Chernobyl
  • High radiation levels forced the evacuation of more than 100,000 people from the region surrounding Chernobyl, but although about 700 residents have since returned to live in the region, none have reoccupied the actual town of Pripyat. (wikitravel.org)
  • The accident that destroyed the Chernobyl 4 reactor is understood to have directly led to the death of 31 reactor operating staff, emergency responders and firemen within three months of the incident. (wikitravel.org)
  • In Chernobyl accident in April 1986, the fatalities includes 28 firefighters who suffered acute radiation disease. (affleap.com)
  • The work focuses on two different situations that both present an important interest for public health: lung cancer associated with domestic radon exposures (natural situation) and thyroid cancer associated with the Chernobyl accident fallout (accidental situation). (irsn.fr)
  • The assessment of thyroid cancer risk in the most exposed area of France due to the Chernobyl nuclear power plant accident fallout, is based on the excess relative risk model published by E. Ron et al. (irsn.fr)
  • The results show that the thyroid cancer incident rate increase observed in France during last 20 years cannot be explained by the Chernobyl fallout. (irsn.fr)
  • electromagnetic
  • Tanning device" means equipment that emits electromagnetic radiation having wavelengths in the air between 200 and 400 nanometers and that is used for tanning of human skin and any equipment used with that equipment, including but not limited to protective eyewear, timers and handrails. (etsu.edu)
  • Estimates
  • Estimates of deaths related to the accident range from 56 to thousands. (wikitravel.org)
  • The estimates are derived by taking correlations in the epidemiological literature between observed pollution levels and health indicators, like hospital admission rates, and then extrapolating across populations to estimate how many deaths and illness diagnoses can, in theory, be attributed to pollution. (wattsupwiththat.com)
  • Employing a hierarchical model for stabilization had little impact on the estimated associations for the most commonly observed outcomes, but for less frequent cancer types, the stabilized estimates tended to take less extreme values and have greater precision than estimates obtained without such stabilization. (ovid.com)
  • Similar risk estimates were observed in the linear ERR model at 10 mSv of cumulative exposure with a 15-year lag. (cdc.gov)
  • Uncertainties associed to risk coefficients and exposures have been quantified and it's impact on risk estimates is calculated. (irsn.fr)
  • Leukemia
  • First, radiation causes a larger percent increase in leukemia rates (but a smaller number of cases since leukemia is relatively rare, even in heavily exposed survivors), and second, the increase appears sooner after exposure, especially in children. (rerf.jp)
  • The average latency for leukemia to develop is ten years while other forms of cancers to develop is twenty years from the time one has exposed to radiation. (affleap.com)
  • 6,000
  • As documented in the report, "indoor tanning is of strong concern because it has been estimated to be related to more than 400,000 cases of skin cancer in the United States each year: 245,000 Basal Cell Carcinomas (BCC), 168,000 Squamous Cell Carcinomas (SCC), and 6,000 melanomas. (etsu.edu)
  • screenings
  • Yet, these breast screenings are considered to be the most effective form of detecting breast cancer, at least according to the Center For Disease Control (CDC). (earth-matters.nl)
  • Another study that was recently published in the British Medical Journal concluded that regular mammogram screenings do not reduce breast cancer death rates. (earth-matters.nl)

  • contrast
  • By contrast, studies of equal population-size which involve the exposure of only a few organs will necessarily have many fewer cancer-cases to evaluate, and thus findings from such studies will be inherently less reliable due to random fluctuations in small numbers. (ratical.org)
  • New screening device provides images with 6 times better contrast of breast tumors and approximately half the radiation dose of standard mammography. (oncologynurseadvisor.com)
  • invasive
  • Concern has been expressed about the fact that cows' milk contains estrogens and could stimulate the growth of hormone-sensitive tumors"-concern that the "consumption of dairy products could [both] promote the conversion of precancerous lesions or mutated cells to invasive cancer and enhance the progression of hormone-dependent tumors. (nutritionfacts.org)
  • tumors
  • These tumors, which arise from non-neuronal cells within the brain, grow quickly and aggressively, and contain a core population of glioma stem cells (GSCs) that are largely invulnerable to the weapons typically brought to bear against other cancers. (phys.org)
  • despite

  • Methods
  • We were looking for predictable, common physical effects from standardized exposure levels," McKitrick said, adding the researchers examined data over a longer time span than most previous studies, and used advanced econometric methods called Bayesian Model Averaging to ensure they considered all possible combinations of effects. (wattsupwiththat.com)
  • This section summarizes the theory, principles, and methods of risk assessment epidemiology for studying exposure-disease relationships. (nap.edu)
  • Evaluation of the association between exposure and disease occurrence is aided by the use of statistical models, and the types of models commonly used in radiation epidemiology are described below, as are the methods for fitting the models to data. (nap.edu)
  • tissue
  • It is the amount of radiation needed to produce damage to a living tissue. (affleap.com)
  • Both dense breast tissue and cancer appear white on an X-ray, thus it's extremely difficult and practically impossible for a doctor to detect cancer with this type of tissue. (earth-matters.nl)
  • uncertainties
  • Similar to almost all other cancer screens, uncertainties exist and persist even after recent scientific efforts and data. (springer.com)
  • We believe that by staying within the characteristics of the original trial and appropriately sharing the evidence as well as the uncertainties, it is reasonable to implement a LDCT lung cancer screening program for smokers and former smokers. (springer.com)
  • occurrence
  • Understanding the role of exposure in the occurrence of cancer in the presence of modifying effects is a difficult problem. (nap.edu)
  • Contributing to the difficulty are the stochastic nature of cancer occurrence, both background and exposure related, and the fact that radiogenic cancers are indistinguishable from nonradiogenic cancers. (nap.edu)
  • The two essential components of risk assessment are a measure of exposure and a measure of disease occurrence. (nap.edu)
  • A common measure of disease occurrence used in cancer epidemiology is the incidence rate . (nap.edu)

  • prostate cancer
  • Does the hormonal stimulation of human prostate cancer cells by cow milk in a petri dish translate out clinically in studies of human populations? (nutritionfacts.org)
  • This was initially postulated based on suggestive population-scale data like this: 25-fold increase in prostate cancer in Japan since the war. (nutritionfacts.org)
  • This recent study represents the other extreme, controlling for as many factors as possible by just isolating prostate cancer cells out of the body in a petri dish, and dripping cow milk on them directly. (nutritionfacts.org)
  • There's kind of two main ways that's done-retrospective studies looking back, where you take prostate cancer patients, and figure out what they ate in the past, and prospective studies looking forward, where you look at people's diets first, and then follow them for a few years, and see who gets cancer. (nutritionfacts.org)
