Science, 1983
The National Academy of Sciences elected 12, not 6, new foreign associates (News and Comment, 3 June, p. 1028). The remaining six are Kimishige Ishizaka (Japan), medicine and microbiology, Johns Hopkins University School of Medicine; Ikuo Kushiro, petrology, University of Tokyo, Tokyo, Japan; Guido Pontecorvo (Italy).

Risk assessment of carcinogens in food
Toxicology and Applied Pharmacology, 2010Approaches for the risk assessment of carcinogens in food have evolved as scientific knowledge has advanced. Early methods allowed little more than hazard identification and an indication of carcinogenic potency. Evaluation of the modes of action of carcinogens and their broad division into genotoxic and epigenetic (non-genotoxic, non-DNA reactive ...

Science, 1977
Carcinogenic risk assessment involves a mixture of statistical, scientific, and public policy considerations. Concepts in current use, such as "no observed effect levels" and "virtual safety," and the problems in implementing them by means of dose-response models, particularly the probit-log dose and linear models are reviewed. The upper limits to risk

1988
Publisher Summary This chapter explains the importance of carcinogen risk assessment. It explains why it is important to assess risk, the legal and regulatory reasons, cancer prevention, avoiding hazards and relationships. The chapter also gives a detailed description upon basic notions of risk assessment, such as risk and rare events, risks to ...

Synthetic risks, risk potency, and carcinogen regulation
Journal of Policy Analysis and Management, 1998This article analyzes a comprehensive sample of over 350 chemicals tested for carcinogenicity to assess the determinants of the probability of regulation. Controlling for differences in the risk potency and noncancer risks, synthetic chemicals have a significantly higher probability of regulation overall: this is due to the greater likelihood of U.S ...

Carcinogenic Risk in Radiotherapy
Tumori Journal, 1968The information on the appearance of skin, bone, thyroid and internal tumors following radiotherapy has been reviewed. As far as the development of leukemias, the data concerning humans are discussed, particularly in relation to the treatment for thymic hypertrophy, spondilitis and hyperthyreotoxicosis.

Carcinogenic potency and risk assessment
Food Additives & Contaminants, 1984An overview of carcinogenesis risk assessment is presented. The nature of evidence for carcinogenic potential in humans is discussed, including possible carcinogenic mechanisms, genotoxicity and laboratory animal data. Emphasis is given to the importance of including all pertinent evidence in risk assessment, rather than placing total reliance on ...

Comparison of teratogenic and carcinogenic risks
Regulatory Toxicology and Pharmacology, 1989Risk assessment for teratogens has received much less attention than carcinogens. This may be due in part to the lack of biologically based dose-response models for teratogens. Also, there appears to be a perception that cancer risks far exceed teratogenic risks for most chemicals.

Carcinogenic Risk Assessment: A Guide to the Literature
Biometrics, 1981An overview of the problems involved in assessing the carcinogenic potential of environmental chemicals is presented. Statistical aspects of the safety evaluation process are noted and appropriate references to the literature are provided. 1. Introducffon As a result of the increasing awareness of the potential health hazards of environmental chemicals,
