TL;DR: Toxicological investigations showed isofenphos plasma decay and confirmed the intramuscular route of poisoning, and it is believed continuous isofanphos absorption resulted in the prolonged intoxication observed in this patient.
Abstract: Case Report: We report a unique case of attempted suicide by intramuscular injection of the organophosphate isofenphos which resulted in a muscarinic and nicotinic syndrome lasting 15 days and requiring prolonged mechanical ventilation and hospitalization. The patient, who demonstrated no signs of delayed polyneuropathy on hospital day 25, subsequently died of pneumonia. Toxicological investigations showed isofenphos plasma decay and confirmed the intramuscular route of poisoning. We believe continuous isofenphos absorption resulted in the prolonged intoxication observed in this patient

TL;DR: In this paper, the radon level was measured inside 88 dwellings, 34 workplaces, and two underground non-uranium mines belonging to the Brazilian states of Rio Grande do Norte and Ceara.
Abstract: In order to assess the natural radioactivity in a developing country with a hot climate, radon concentrations were measured inside 88 dwellings, 34 workplaces, and two underground non-uranium mines belonging to the Brazilian states of Rio Grande do Norte and Ceara. The determinations were performed in the selected settings using solid state nuclear track detectors which were exposed for a period of time of the order of 180 days between the months of June 1995 and April 1996. The indoor radon level was found to range from 3.2 to 140 Bq.m -3 with geometric means of 12.4 Bq.m -3 for houses, and 15.1 Bq.m -3 for workplaces (schools, hospitals, offices, and so on). These relatively low values are probably related to elevated ventilation rates which are typical of edifices located in Northeast Brazil. The average radon concentrations in the surveyed scheelite mines were 153 and 503 Bq.m -3 , respectively.

TL;DR: In this article, the background airbome radioactivity in the town of Natal, Brazil was determined using solid state nuclear track detectors which were exposed for a period of about 180 days.
Abstract: The aim of this work was to determine the background airbome radioactivity in the town of Natal, Brazil. Indoor radon concentrations were measured inside 24 buildings using solid state nuclear track detectors which were exposed for a period of about 180 days. The average indoor radon level resulted to be 15.4±10.6 Bq·m−3. Measurements of gross α- and β-activities were performed at six different sites for airbome particulate samples collected over cellulose nitrate filters. Mean values of 0.15±0.06 mBq·m−3 and 0.42±0.10 mBq·m−3 were obtained for the gross α-and gross β-activity, respectively.
