Title Radioactive well logging: A review and an analysis of Texas incidents
Bibliographic information Mar. 1981, Vol.40, No.3, p.361-368. Illus. 14 ref.
Abstract The health physics considerations of the transportation, handling and use of radioactive sources in oil and gas well logging operations are discussed. Gamma and neutron sources are transported to well sites in shielded containers and then lowered, by wire-line service personnel, into wells. The subsurface structure is mapped as the source is drawn up. Exposure of personnel can occur as a result of inadequate shielding or handling practice or leaks in containers, e.g. as a result of road accidents. Down-hole losses of the sources present environmental hazards. Texas records between 1957 and 1976 showed that 12.6% of total radiation incidents reported were related to the logging industry. Over-exposures due to well logging incidents compared favourably with those experienced in radiography, research and education fields.
