A novel methodology combining digital imaging, conventional fixed visibility monitors, and solar radiation monitors has been developed to characterize the visual air quality of the El Paso and Ciudad Juarez urban vista. The authors have found that th

One of two topics explored is the limitations of the daily average in summarizing pollutant hourly profiles. The daily average of hourly measurements of air pollutant constituents provides continuity with previous studies using monitoring technology

The authors are completing a 30-year study of the biological effects of {sup 90}Sr and {sup 226}Ra in the beagle in order to predict the possible long-term hazards to people from chronic exposure to low levels of irradiation. Animals received either

Data for the bone-by-bone redistribution of 90Sr in the beagle skeleton are reported for a period of 4000 d following a midgestation-to-540-d-exposure by ingestion. The partitioned clearance model (PCM) that was originally developed to describe bone-

A total of 155 primary bone sarcomas were found in 131 of the 246 beagles injected with 226Ra and 5 primary bone sarcomas were found in 4 of the 158 unexposed controls. Of these 155 bone sarcomas, 146 (94%) were osteosarcomas and 9 were non-osteosarc

A total of 66 primary bone sarcomas were diagnosed in 47 beagles; 43 of these dogs were part of the 403 beagles fed 90Sr and 4 were part of the 162 controls. Multiple primary bone sarcomas were found in 15 of the 47 beagles (32%). The incidence of mu

Skeletal uptake and retention of graded doses of ingested or injected90 Sr and injected226 Ra have been studied in 863 beagles; measurements of skeletal burden were made up to a maximum lifetime of 18.5 years. Doses ranged from 0 in 162 controls to l

The distribution of 226Ra activity among the bone groups of the skeleton has been measured as a function of time after exposure for 12 beagles. The dogs were given 8 semi-monthly injections of radium totalling 0.37 microCi/kg, 1.11 microCi/kg, or 3.3

The bombardment of a 10–15 atm high purity O2 target with a 5–10 μA beam of 15 MeV protons produces 13N(t12 = 9·96 min) by the 16O(p,α) 13N nuclear reaction. The nitrogen atoms are incorporated into the primary products, 13N2, 13N2O and 13NO2
