In order to focus on more of the basic research problems related to radon, a symposium was organized in conjunction with the 191th National Meeting of the American Chemical Society. This volume presents most of the reports given at that symposium. There are five major groups of reports occurrence, measurement methods, physical and chemical properties of radon and its decay products, health effects, and mitigation of radon levels.

Mobility of Uranium and Radon associated with uranium roll front occurrences in the Horton Group of the Windsor area, Nova Scotia,... 

Fig. 2. Location of Green Street Occurrence and related radon soil gas and well water anomalies.

The initial exploration and subsequent drilling in the Windsor area was sparked by the discovery of radon anomalies in the soil gas and well waters in the area (Quarch et al. 1981 Fig. 2). In addition, uranium and radium in well waters were weakly anomalous in the area. It is therefore not difficult to infer that these geochemical techniques are useful exploration tools for deposits of this type and that there are environmental Issues related to uranium occurrences in the Horton Group. 

Although this paper deals primarily with uranium and radon from occurrences in the Windsor area of Nova Scotia, the areal extent of the Horton Group strata throughout eastern Canada would seem to imply that environmental issues related to the Horton Group uranium mineralization might exist throughout the Maritimes Basin.

The 1996 Amendments further require EPA to establish a mechanism to identify and select new contaminants, as well as specific efforts to establish criteria for arsenic, sulfates, radon, and disinfection by-products. The SDWA required EPA to establish a list of contaminants every five years that are known or anticipated to occur in public water systems and may require further investigation and possible regulation under SDWA. The list is divided into those materials that are candidates for additional research, those that need additional occurrence data, and those that are priorities for consideration in rulemaking. The EPA then must prioritize the critical substances in each category and develop a plan of action for making regulatory decision for the most appropriate candidates.
