Abstract

The natural radioactivity of ²²⁶Ra and ²²⁸Ra in scale samples taken from pipes used in several local water wells was investigated. The results showed ²²⁶Ra activities to be varying from 1284 to 3613Bq/kg whereas, the ²²⁸Ra concentrations did not show any significant variation, all being low, below 30Bq/kg. The ²²²Rn exhalations from these scale samples were also measured and compared with the ²²⁶Ra contents. The average ratio of ²²²Rn/²²⁶Ra was 31%. Chemical analyses showed that the main constituent of the scale samples was iron. The radiation dose rates from the pipes and scale were up to 100nSv/h. Although not a major hazard this could present a long-term risk if the scale materials were handled indiscriminately.
