MODELING NONLINEAR DOSE-RESPONSE RELATIONSHIPS IN EPIDEMIOLOGIC STUDIES: STATISTICAL APPROACHES AND PRACTICAL CHALLENGES
- The Healthy Worker Effect and Nuclear Industry Workers. Fornalski, Krzysztof W.; Dobrzyński, Ludwik // Dose-Response;2010, Vol. 8 Issue 2, p125
The linear no-threshold (LNT) dose-effect relationship has been consistently used by most radiation epidemiologists to estimate cancer mortality risk. The large scattering of data by International Agency for Research on Cancer, IARC (Vrijheid et al. 2007; Therry-Chef et al. 2007; Cardis et al....

- Low-Dose Cancer Risk Modeling Must Recognize Up-Regulation of Protection. Feinendegen, Ludwig E.; Pollycove, Myron; Neumann, Ronald D. // Dose-Response;2010, Vol. 8 Issue 2, p227
Ionizing radiation primarily perturbs the basic molecular level proportional to dose, with potential damage propagation to higher levels: cells, tissues, organs, and whole body. There are three types of defenses against damage propagation. These operate deterministically and below a certain...
- A Role for Bioelectric Effects in the Induction of Bystander Signals by Ionizing Radiation? Mothersill, C.; Moran, G.; McNeill, F.; Gow, M. D.; Denbeigh, J.; Prestwich, W.; Seymour, C. B. // Dose-Response;2007, Vol. 5 Issue 3, p214
The induction of "bystander effects" i.e. effects in cells which have not received an ionizing radiation track, is now accepted but the mechanisms are not completely clear. Bystander effects following high and low LET radiation exposure are accepted but mechanisms are still not understood. There...
- Comparison of adsorbed skin dose received by patients in cone beam computed tomography, spiral and conventional computed tomography scanninng. Ghazi, K. Sani Khanlou; Eskandarlou, A.; Rostampour, N.; Rahimi, A. // Journal of Dental Medicine;2011, Vol. 24 Issue 2, p181
Background and Aims: The evaluation of absorbed dose received by patients could give useful information for radiation risk estimation. This study was performed to compare the entrance skin dose received by patients in cone beam computed tomography (CBCT), conventional and spiral computed...
- Radiological Assessment for Bauxite Mining and Alumina Refining. O’connor, Brian H; Donoghue, A Michael; Manning, Timothy J H; Chesson, Barry J // Annals of Occupational Hygiene;Jan2013, Vol. 57 Issue 1, p63
Objective: Two international benchmarks assess whether the mining and processing of ores containing Naturally Occurring Radioactive Material (NORM) require management under radiological regulations set by local jurisdictions. First, the 1 Bq/g benchmark for radionuclide head of chain activity...

- STATISTICAL CHALLENGES IN EVALUATING DOSE-RESPONSE USING EPIDEMIOLOGICAL DATA. Mundt, Kenneth A. // Dose-Response;2005, Vol. 3 Issue 4, p453
The article discusses various reports published within the issue, including one by Kenny S. Crump on the impact of random error on the assessment of the shape of the dose-response and another by Edwin van Wijngaarden on graphical approach for uncovering dose-responses.
- Lose-Dose Abdominal CT for Appendicitis. Kuritzky, Louis // Internal Medicine Alert;6/15/2012 Supplement, p87
The article informs that the use of low-dose abdominal computed tomography (AB-CT) scan to diagnose appendicitis is as effective as high-dose AB-CT.
