As part of ongoing efforts to assess lifespan disease mortality and incidence in 63,715 patients from the Canadian Fluoroscopy Cohort Study (CFCS) who were treated for tuberculosis between 1930 and 1969, we developed a new FLUoroscopy X-ray ORgan-spe

Organ Doses from Chest Radiographs in Tuberculosis Patients in Canada and Their Uncertainties in Periods from 1930 to 1969

Autor: Brian A. Thomas, Choonsik Lee, Lydia B. Zablotska, A. Iulian Apostoaei, David Borrego, David C. Kocher

Publikováno v: Health Physics

This paper describes a study to estimate absorbed doses to various organs from film-based chest radiographs and their uncertainties in the periods 1930 to 1948, 1949 to 1955, and 1956 to 1969. Estimated organ doses will be used in new analyses of ris

NCRP Report 181, Evaluation of the Relative Effectiveness of Low-energy Photons and Electrons in Inducing Cancer in Humans: A Critique and Alternative Analysis

Autor: David C. Kocher, F. Owen Hoffman

Publikováno v: Health physics. 116(6)

A recent report from the National Council on Radiation Protection and Measurements presents an evaluation of the effectiveness of low-energy photons and electrons, relative to higher-energy photons, in inducing cancer in humans. The objective of that

PROBABILITY DISTRIBUTION OF DOSE AND DOSE-RATE EFFECTIVENESS FACTOR FOR USE IN ESTIMATING RISKS OF SOLID CANCERS FROM EXPOSURE TO LOW-LET RADIATION

Autor: A. Iulian Apostoaei, David C. Kocher, F. Owen Hoffman, John R. Trabalka

This paper presents an analysis to develop a subjective state-of-knowledge probability distribution of a dose and dose-rate effectiveness factor for use in estimating risks of solid cancers from exposure to low linear energy transfer radiation (photo

DRINKING WATER STANDARD FOR TRITIUM—WHAT'S THE RISK?

Autor: F. O. Hoffman, David C. Kocher

Publikováno v: Health Physics. 101:274-285

This paper presents an assessment of lifetime risks of cancer incidence associated with the drinking water standard for tritium established by the U.S. Environmental Protection Agency (USEPA); this standard is an annual-average maximum contaminant le

Autor: Gordon R. Bilyard, Kathryn A. Higley, David C. Kocher, S. Domotor, Daniel S. Jones

Publikováno v: Journal of Environmental Radioactivity. 66:19-39

This paper provides a bridge between the fields of ecological risk assessment (ERA) and radioecology by presenting key biota dose assessment issues identified in the US Department of Energy's Graded Approach for Evaluating Radiation Doses to Aquatic

Derivation of a screening methodology for evaluating radiation dose to aquatic and terrestrial biota

Autor: S. Domotor, David C. Kocher, Ernest J. Antonio, Kathryn A. Higley

Publikováno v: Journal of Environmental Radioactivity. 66:41-59

The United States Department of Energy (DOE) currently has in place a radiation dose standard for the protection of aquatic animals, and is considering additional dose standards for terrestrial biota. These standards are: 10 mGy/d for aquatic animals
