Gamma Exposure from Rn Progeny in GAC Units
An investigation into the gamma exposure rate generated by granular activated carbon (GAC) water treatment units focused on ten sites that covered a range of source radon (Rn) in water...

Technical Issues Related to Emission Releases from Subslab Radon Mitigation Systems
Surveys of government and private sector radon mitigation activities indicate that subslab radon mitigation systems account for more than 50 percent of all installed systems. Such systems...

Radon Resistant New Construction Practices
This paper highlights the basic principles for building radon-resistant houses and it groups the construction techniques into four categories, i.e., the barrier approach, soil ventilation...

Indoor Radon: Site Evaluation
The soil parameters most important in evaluating the indoor radon potential of a building site are the soil radium concentration, the soil-gas radon concentration and the permeability...

Pressure Differences Affecting Radon Entry in New Residential Construction
Various conditions in a house can commonly produce house negative pressures up to 20 Pascals relative to the soil gas pressure. Depressurization of the house relative to the soil gas will...

Cost of Radon Control Measures in New Construction
Installation of a radon prevention system in new construction increases costs to builders and to homebuyers as well. Builders and/or their engineers will need to assess different approaches...

Review of Uranium Tailings Cover Design

Radon at Home
Radon-222 is a radioactive gas that is present in all homes and found in several million homes in the U.S. at levels that have medical experts concerned about its potential to cause lung...

Burying the Nuclear Past
The Uranium Mill Tailings Remedial Action Program involves reclaiming 24 tailings piles. The work is done in terms of Federal Legislation to prtect the environment and people from the...

Environmental Geotechnology & Tailings Reclamation
The Department of Energy is responsible, in terms of Federal Legislation, for remedial action work at 24 inactive uranium mill tailings piles in ten states. This paper describes the setting...

Rn-222 and Ra-226 in Ground Water

Removal of Radon and Uranium from a water supply
The removal of Radon and Radium from drinking water with the help of granulated activated carbon (GAC) adsorption was investigated. A packed bed column was used for the purpose. It has...

Health Effects,Risk Assessment and Guidance for Indoor Radon
Unlike many inorganic elements, radionuclides have no nutritional value. Radionuclides are carcinogenic and uranium is also known to be non-carcinogenic as well. This paper is primarily...

Treatment Facilities and Costs for the Removal of Radon from Ground Water Supplies
Two methods for removal of Radon from drinking water are considered: activated carbon adsorption and packed tower aeration. Although both granular activated carbon (GAC) and packed tower...

Design of a GAC Water Treatment System for Radon
The author describes the design of a granular activated carbon (GAC) treatment system for the removal of radon from a public water supply....
