Exposure and Dose: Health Effect Studies Associated with Nanometer Aerosols Lev S. RuzerLawrence Berkeley National Laboratory, USA AbstractThe nanotechnology industry is rapidly growing with promises of substantial benefits that will have significant global economic and scientific impacts applicable to a whole host of areas from engineering and electronics to environmental remediation and medical healthcare. However, at present there is growing concern over the safety of nanomaterials with respect to occupational, consumer and environmental exposures and associated health effect. Particularly, information on nanomaterial exposure, dosimetry, risk assessment and health effect is negligible. In this paper we discussed the problems of the Exposure and Dose in the studies of the health effect related to nanoaerosols. As a general plan for the assessment of the Dose -the main cause of the effect -Nanoparticles Dosimetric Road Map is presented. The new ideas for measurement of the surface area of nanoparticle, local nanoparticle lung deposition, and nanoparticles respirators true effectiveness are proposed.

Toxicity Issues Related to Biomedical Applications of Carbon Nanotubes

“…As the large scale production and utilization of nanomaterials increase, so does the risk to human health and environment. The toxic effects of CNTs and other nanomaterials are not fully characterized, and as the field grows, the need for standardization and categorization will increase so that results can be compared and analyzed for potential risks [137]. As per the US Environmental Protection Agency (EPA), CNTs are regarded as a "chemical substance" under the toxic substances control act (TSCA).…”

Characterization of environmental radiological parameters on dose coefficient - Realistic dosimetry compared with epidemiological dosimetry models

“…The unattached activity constitutes about 10% of the total activity but contributes 50% of the total radiation dose. Ruzer conducted experiments on the correlation between the unattached fraction of radon decay products and the aerosol surface area [ 13 ].…”
