26. Hanford radiation study III: a cohort study of the cancer risks from radiation to workers at Hanford (1944-77 deaths) by the method of regression models in life-tables.
This paper reports on results from the study initiated by Mancuso into the health risks from low-level radiation in workers engaged in plutonium manufacture at Hanford Works, Washington State, USA, and attempts to answer criticisms of previous reports by an in-depth study. Previous reports have aroused much controversy because the reported risk per unit radi

31. Identification of occupational mortality risks for Hanford workers.
Though most of the production work at Hanford is done by manual workers, 46% of the most dangerous jobs are performed by people who have professional or technical qualifications. For these privileged workers occupational mortality risks are positively correlated with radiation doses but for manual workers, who have relatively high death rates, there is an in

33. The estimation of risks from the induction of recessive mutations after exposure to ionising radiation.
Since recent assessments of genetic risks from radiation have concentrated on harmful dominant effects, a quantitative assessment of risks from recessives is needed. Presumably, harmful recessives can arise at all loci coding for essential proteins (perhaps 10 000), but mutation to dominant alleles is likely to be a property of relatively few loci. While man

34. Transvenous coronary angiography in humans using synchrotron radiation.
The risks and costs of the present method of visualizing the coronary arteries have limited the use of coronary angiography in long-term serial studies needed to establish the natural history of coronary atherosclerosis and its response to interventions. A less invasive method, in which the contrast agent is administered intravenously, has been developed usi

35. Risk factors for radiogenic cancer: a comparison of factors derived from the Hanford survey with those recommended by the ICRP.
A model for cancer induction in man exposed to low doses of radiation and based on the analysis of a survey of workers from a nuclear fuel processing plant is examined and compared with that adopted by the ICRP to limit risks to radiation workers. It is shown that claims that ICRP has significantly underestimated the risk apply primarily to those exposed in

36. Evaluation of the Effects of Chemical Mutagens on Man: The Long Road Ahead*
By analogy with the problem of evaluating the genetic risks of radiation, it appears that it will be extremely difficult to assess the mutagenicity for man of the wide range of chemicals to which human populations are currently exposed. Nevertheless, the potential significance of this problem calls for a major effort at such an evaluation.
