Apr 14, 2021 To reduce the risk of lung cancer from exposure to radon, EPA recommends testing all homes for radon, regardless of whether the home contains granite countertops. Call 1-800-SOS-RADON (767-7236) or purchase do-it-yourself home radon test kits at home store retail locations, or online. Testing is inexpensive and easy—it should only take a few

Radon Exposure No Concern to Quarry Workers. April 2014 — In order to extract the beautiful granite rock that adorns so many countertops, floors and building facades in the United States, skilled quarry workers must saw or blast the raw granite into blocks to remove it from the quarry location for further fabrication. Given that soil and rock slowly and naturally emit radon gas, some sought

Assessment of Radionuclides in Selected Granite Quarry

Assessment of Radionuclides in Selected Granite Quarry

Granite quarries produce massive amount of dust particles and such dust particles increase the level of Radon gas [10]. The main way of saving the humans from radiation injuries is to protect it from exposure to radiation and this is why radiation monitoring and measurement are very essential in our society today. 2. Experimental Procedure
