A representative sample of over 2,000 UK dwellings was monitored for a year using thermoluminescent and etchable plastic dosemeters to measure gamma ray dose rates and radon concentrations. 

Models have been developed to enable prediction to be made of the dose incurred indoors from gamma radiation and from inhalation of radon decay products. 

The National Radiological Protection Board has undertaken a large scale environmental survey of radiation levels in homes throughout the United Kingdom. Passive radon and gamma ray dosemeters were posted to a representative sample of households. Lithium fluoride thermoluminescence dosemeters were used to assess natural gamma radiation and were left in the measurement location for a period of six months before being returned to the Board for processing. As a preliminary to the national survey, several limited surveys were undertaken in regions of igneous and sedimentary geology.

Contains references and abstracts on laboratory techniques for analyzing formaldehyde, methodologies for identifying and characterizing a wide variety of organic contaminants and selected field studies of organic contaminants inindoor air.

Discusses the sources and concentrations of organic compounds in indoor environments. Describes work done by the Lawrence Berkeley Laboratory in the USA on formaldehyde and poor air quality in offices.

Describes a project for the design, construction and evaluation of a mechanical ventilation system of small dimensions, easy installation and extreme simplicity.

Infiltration heat loss has become more important in the energy loss of modern buildings. It depends on a variety of factors. Computer analysis points to the effect of storey number, ground plan features and exhaust ventilation systems. Different rooms exhibit infiltration heat loss maxima at different outdoor temperatures.

Summarizes a study reviewing indoor air pollution in housing in Canada. Concludes that 1, many materials and conditions which contribute significantly to indoor air pollution are known to be present in Canadian houses, 2,individual susceptibility to air pollution varies, 3, smoking remains a major source of pollution, 4, some energy conservation measures aggravate indoor pollution problems, 5, the full health, social and economic costs have yet tobe determined, and 6, acceptable levels of effects on health have not been defined.

This paper describes a framework and methodology for developing and evaluating surveys of occupants for indoor air quality studies. Factors to be studied, and how they can be classified, are addressed. How the often substantial information can be obtained in a stepwise fashion without burdening theparticipant unduly, and ways of judging the efficacy of the questions are also discussed.

The effect of reduced air infiltration rate caused by energy-saving measures has been studied by comparing the indoor climate in 25 sealed apartments with the conditions in 25 unsealed apartments in Denmark in four seasonal periods.
