Occupational exposure due to naturally occurring

The potential occupational exposure in granite quarry industry due to the presence of naturally occurring radioactive material (NORM) has been investigated. The activity concentrations of (40)K, (226)Ra and (232)Th were determined using gamma-ray spectroscopy method.

radiation measurements are for low radiation field. The radiation measurement method used in this work was a direct observation and measurement of radiation level from various granite sites locations visited with the radiation inspector. The background radiation within the environment was measured

Radon Exposure from Granite: Debunking Health Concerns

Radon Exposure from Granite: Debunking Health Concerns. Like all stone, granite contains trace amounts of radium, which decays over time into a naturally-occurring gas called radon, emitting low levels of radiation. Stone quarry workers are surrounded by massive amounts of granite on a daily basis. Should they be concerned about their health?

Radon Exposures in Granite Quarry Natural Stone Institute

Radon Exposures in a Granite Quarry EXECUTIVE SUMMARY Multiple studies have been published demonstrating that exposures to both radon and direct radiation from granite countertops are very low, and that this is not an issue of concern for homeowners (Allen et al., 2010; Chen et al., 2010; Myatt et al., 2010; Llope, 2011; Allen et al., 2013).

Full gear unit range for your horizontal mill FLSmidth

We often see ball mills used for clinker grinding, while vertical mills tend to be more common today for raw material comminution. In older cement plants, however, both process steps are equipped with ball mills and their corresponding drive systems. But many of these gear units have seen better days and might no longer satisfy your needs.
