Is indoor radon linked to leukaemia in children and adults
The evidence linking indoor radon exposure to childhood and adult leukaemia is reviewed. At the UK average indoor exposure of 20 Bq m, it is estimated that the radon derived equivalent dose accrued to the fetus is 106 μSv. The equivalent dose rate to adult bone marrow ~130 μSv y. Standard radiation risk factors suggest that 5% of childhood and 4% of adult leukaemia is linked to radon at 20 Bq m...
متن کاملChildhood leukaemia Genetics and Ionising Radiation
The list of chromosome changes and gene mutations in leukaemia is now very extensive, involving more than 100 identified genes and including changes that are leukaemia subtype specific (Mullighan 2007, Han 2010, Oh 2010, de Jesus Marques-Salles 2010), or country -specific. Siddiqui found (2010) that a particular fusion gene was found in Pakistan, Myanmar and Sudan, at a much lower rate than rep...
متن کاملAssessment of indoor cancer linked to accumulated radiation dose from different types of television sets in dwellings
Exposure to radiation from different types of television sets was measured to ascertain the levels of hazards posed to the human biological system. Measurement of the annual radiation dose hazards was performed using a halogen-quenched GM tube with thin mica end window having a density of 1.5 mg/cm2, effective window diameter of 0.360 inch and side wall of 0.012 inch thick. The GM tube was plac...

متن کاملThe risk linked to ionizing radiation: an alternative epidemiologic approach.
Radioprotection norms have been based on risk models that have evolved over time. These models show relationships between exposure and observed effects. There is a high level of uncertainty regarding lower doses. Recommendations have been based on the conservative hypothesis of a linear relationship without threshold value. This relationship is still debated, and the diverse observations do not...
