Describes the different types of monitoring and sampling techniques that can determine the radiation burden of the general public from radon and its decay products. This is accomplished by measuring the range and distribution of radon and rad
Simulation methods and test results are presented here to confirm projections of actual total suspended particulate (TSP) concentration levels for representative office buildings, with particular emphasis on the 0.3 to 5 micron particulate si
The U.S. EPA initiated an indoor air monitoring program in 1982, concentrating on commercial or public-access buildings (homes for the elderly, schools, and office buildings). Several buildings from each category are sampled over 2-3 day peri
It is only recently that indoor air pollution has begun to attract the attention it deserves in Canadian Governmental and Building code circles. Two main events have been catalytic towards this increased emphasis. First, the ban on the use of ur
During the last fifteen years Urea-Formaldehyde (UF) bonded particle board, medium density fiberboard and plywood have replaced whole wood as a construction material for flooring, wall panelling cabinet work and furniture. At the same time,
The use of urea formaldehyde resins in Canadian houses, the mechanism of formaldehyde releases, health effects, toxicity, carginogenicity, allergic reactions and standards for ventilation are discussed.
The quantity of air in several rooms lying in a stack connected by means of fresh air and exhaust air ducts is considered as a simple model of amultistorey building. Negative pressures set up within the rooms can be equalised by adjusting the
Results of air quality measurements are presented for a group of low-leakage houses located in Saskatoon, Saskatchewan. A total of 46 houses were tested for formaldehyde, nitrogen dioxide, radon, and humidity levels. The median level of formalde
In response to employee complaints of upper respiratory and eye irritation, formaldehyde air sampling studies were conducted in two different office environments. The first was in a series of temporary modular buildings with construction simi
In large areas of the Swiss Alps, the high radium content of rocks and soil, which results in high source terms for radon from the ground, may produce considerable indoor levels of radon in dwellings with low air infiltration. During the winter
