Radiofrequency Exposure Levels in Greece
Bioelectromagnetics, 2023Medical Physics Department (Medical School, University of Thessaly) participated in a Greek National EMF research program (EDBM34) with the scope to measure and evaluate radiofrequency (RF) exposure (27–3000 MHz) in areas of sensitive land use. A thousand (1000) measurements were carried out at two “metropolitan locations” (Athens and Thessaloniki: 624

Noise Exposure: Action Level Criteria as a Predictor of Permissible Exposure Level Criteria
American Industrial Hygiene Association Journal, 1983The adoption of the OSHA noise amendment has made it necessary to make two different noise exposure measurements. These are the employee's exposure with reference to the action level criteria, which requires a threshold of 80 dBA, and the employee's exposure with reference to the permissible exposure limit, which employs a 90 dBA threshold. In addition

Exposure levels and determinants of inhalable dust exposure in bakeries
The Annals of Occupational Hygiene, 1997The study's objectives were to measure full-shift exposure to inhalable dust in bakeries and define the determinants of full-shift exposure. Inhalable dust was measured gravimetrically. Ninety-six bakery workers, employed in seven different bakeries, participated in the study.

Safe Level for Noise Exposure?
Annals of Otology, Rhinology & Laryngology, 1976The safety of long, continuous exposure to several different levels of noise was determined. Chinchillas were exposed for two or nine days to an octave band of noise with a center frequency of .5 kHz or 4 kHz. By examining the inner ear for evidence of acute cellular degeneration, exposures which produced minimal permanent damage could be identified ...

Low-Level Cadmium Exposure and Atherosclerosis
Current Environmental Health Reports, 2021Cadmium has been recognized as a potential risk factor for cardiovascular disease (CVD). We present a review of cadmium toxicity, its effect on cellular activities, and a summary of reported association between environmental cadmium exposure and CVD. We also discuss the possible therapeutic benefit of cadmium chelation.Experimental data suggest that ...

Occupational noise exposure and hearing levels
American Industrial Hygiene Association Journal, 1981A study was made at the Bhabha Atomic Research Center to measure the hearing levels of persons working in a noisy environment. Two different workplaces, central air-conditioning plant and glass flowing shops, where a number of persons were exposed to noise levels exceeding 85 dB(A) were chosen.

Low‐level lead exposure and children
Journal of Paediatrics and Child Health, 2001Abstract: The adverse effects of environmental lead exposure on the mental development of young children are well established. There is no safe level of blood lead below which children are not affected. Recent research expands our understanding of the impact of lead exposure continuing into later childhood, as well as its effects on children’s ...

Dose level of occupational exposure in China
Radiation Protection Dosimetry, 2007This paper discusses the dose level of Chinese occupational exposures during 1986-2000. Data on occupational exposures from the main categories in nuclear fuel cycle (uranium enrichment and conversion, fuel fabrication, reactor operation, waste management and research activity, except for uranium mining and milling because of the lack of data), medical

A Proposal for a Safe Exposure Level for Diacetyl
International Journal of Occupational and Environmental Health, 2011Diacetyl is a naturally occurring compound that has been used in concentrated form as a food additive, particularly in butter flavorings. Inhalation of diacetyl and butter flavoring fumes has caused a variety of respiratory diseases in workers and consumers including bronchiolitis obliterans (BO), a relatively rare, severe, and irreversible lung ...

Farm Equipment Noise Exposure Levels
American Industrial Hygiene Association Journal, 1968Abstract Noise levels recorded during performance tests conducted at the College of Agriculture, University of Nebraska, on 58 new tractors and 20 other types of farm machinery were of such intensity, duration, and distribution as to indicate a potential permanent noise-induced hearing loss to the agricultural worker.
