Radon Exposures in a Granite Quarry ENVIRONMENTAL HEALTH & ENGINEERING, INC. |Environmental Health & Engineering www.eheinc.com 1 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 ofRadon Exposure from Granite: Debunking Health,Although radon exposure from granite countertops is not a legitimate concern, radon exposure from other sources can pose health and safety concerns for homeowners. According to the United States Environmental Protection Agency , “Radon originating from the soil beneath homes is a more common problem and a far larger public health risk than radon from granite building materials.”Natural Stone Institute - Granite and Radon Myths,Radon/Radiation Research. November 2013 — Radon Exposures in a Granite Quarry Findings: Based on the review of available data and radon measurements, occupational exposures and health risks related to radon for granite quarry workers are insignificant, i.e., below average background levels.

Radiation From Granite Countertops Fact Sheet

As indicated in the write‐up, the average radiation exposure measurement from a granite slab was 20 μR h-1. Based on field experience comparing the type of detector used to take the measurements and what is considered the “gold” standard (a pressurized ion chamber), the detector overresponds by as much as a factor of two where the uranium decay series is of concern. Our starting factor,Radiation Exposure Level in some Granite Quarry sites,,Radiation exposure level in some granite quarr y sites in Ohimini and Gwer-East Local Government Areas of Benue State was carried out using radiation meter (radiation alert inspector). The research investigated only the exposure dose rate, the mean absorbed dose and the mean annual effective dose equivalent of the radiation.

Do granite countertops emit radiation? |

Do granite countertops emit radiation? If present, uranium, thorium or radium will decay into radon, a colorless, odorless, radioactive gas that may cause lung cancer. In addition to radon, naturally occurring radioactive elements in the granite can emit small amounts of beta and gamma radiation .Investigation of the Radiation Exposure Rate and Noise,,Keywords: Radiation Exposure, Noise level, Quarry site, Radiation survey, Noise survey 1. INTRODUCTION Radionuclides that were part of the original composition of the earth and their progenies emit gamma radiation which contributes to a large share of environmental radiation dose [1].
