Radon and Its Decay Products in Indoor Air by William W. Nazaroff,Anthony V. Nero Pdf
In recent years, the perception of indoor radon as a relatively minor health issue has been radically altered: observations in Sweden, Canada, and the U.S. have revealed the high incidence of elevated radon levels in ordinary houses and the extreme hazard of inhaling radon decay products. These findings have lead to a wide range of activities and intensive research aimed at limiting human exposure to radon. This is one of the few books to provide a comprehensive, insightful analysis of the radon problem. Papers reflecting the most current research critically review all major aspects of this issue, each providing sufficient detail to be accessible to those who are technically trained but lack prior direct experience. Coverage includes the generation and migration of radon in source material, the physical and chemical behavior of radon, current evidence on the health effects and risk of exposure, and the strategic and tactical aspects of controlling exposures.
WHO Guidelines for Indoor Air Quality by Anonim Pdf

The substances considered in this review, i.e. benzene, carbon monoxide, formaldehyde, naphthalene, nitrogen dioxide, polycyclic aromatic hydrocarbons (especially benzo[a]pyrene), radon, trichloroethylene and tetrachloroethylene, have indoor sources, are known in respect of their hazardousness to health and are often found indoors in concentrations of health concern. The guidelines are targeted at public health professionals involved in preventing health risks of environmental exposures, as well as specialists and authorities involved in the design and use of buildings, indoor materials and products. They provide a scientific basis for legally enforceable standards.
Design and Conduct of Indoor Radon Surveys by IAEA Pdf
This Safety Report draws on the requirements of international standards and the recommendations of international organizations as well as on the scientific literature, together with direct experience from a number of IAEA Member States in relation to carrying out representative indoor radon surveys. The need for and the purpose of representative indoor radon surveys are discussed, as are the factors that must be considered in designing and carrying out such surveys. How the measurement data obtained from indoor radon surveys can be used to develop radon risk maps is also considered. While the Safety Report is focused specifically on national and regional surveys to evaluate average concentrations of radon in dwellings, many of the same considerations also apply to radon surveys for other types of buildings.

Establishing a Dialogue on Risks from Electromagnetic Fields by World Health Organization. Radiation and Environmental Health,World Health Organization Pdf
Public concern over possible health effects from electromagnetic fields (EMF) has led to the preparation of this handbook. Potential risks of EMF exposure from facilities such as power lines or mobile phone base stations present a difficult set of challenges for decision-makers. The challenges include determining if there is a hazard from EMF exposure and what the potential health impact is. Responding to these challenges requires the involvement of individuals or organizations with the right set of competencies combining relevant scientific expertise strong communication skills and good judgement in the management and regulatory areas. This handbook is intended to support decision-makers faced with a combination of public controversy scientific uncertainty and the need to operate existing facilities and/or the requirement to site new facilities appropriately. Its goal is to improve the decision-making process by reducing misunderstandings and improving trust through better dialogue. The guide may assist the general public when interacting with government agencies that regulate environmental health and with companies whose facilities may be sources of concern. References and suggestions for further reading are included.
Handbook of Indoor Air Quality by Yinping Zhang,Philip K. Hopke,Corinne Mandin Pdf
People live in indoor environment about 90% of lifetime and an adult inhales about 15 kg air each day, over 75% of the human body’s daily mass intake (air, food, water). Therefore, indoor air quality (IAQ) is very important to human health. This book provides the basic knowledge of IAQ and highlights the research achievements in the past two decades. It covers the following 12 sections: introduction, indoor air chemicals, indoor air particles, measurement and evaluation, source/sink characteristics, indoor chemistry, human exposure to indoor pollutants, health effects and health risk assessment, IAQ and cognitive performance, standards and guidelines, IAQ control, and air quality in various indoor environments. It provides a combination of an introduction to various aspects on IAQ studies, the current state-of-knowledge, various advances and the perspective of IAQ studies. It will be very helpful for the researchers and technicians in the IAQ and the related fields. It is also useful for experts in other fields and general readers who want to obtain a basic understanding of and research advances in the field of IAQ.

ICRP PUBLICATION 126 by International Commission International Commission on Radiological Protectio Pdf
In this report, the Commission provides updated guidance on radiological protection against radon exposure. The report has been developed considering the latest ICRP recommendations for the system of radiological protection, all available scientific knowledge about the risks of radon, and the experience gained by many organisations and countries in the control of radon exposure. The report describes the characteristics of radon exposure, covering sources and transfer mechanisms, the health risks associated with radon, and the challenges of managing radon exposure. The Commission recommends an integrated approach for controlling radon exposure, relying as far as possible on the management of buildings or locations in which radon exposure occurs, whatever the use of the building. This approach is based on the optimisation principle, and is graded reflecting the responsibilities of key stakeholders, notably in workplaces, and the intent of the national authorities to control radon exposure. The report also provides recommendations on managing radon exposure when workers’ exposures are considered as occupational, and the appropriate requirements of the Commission should be applied.
