Title

Natural radioactivity of some Egyptian materials used in glasses manufacturing and glass ceramics

Pages

  207-215

Abstract

 Background: The new glasses from harmful environmental waste such as cement dust; limestone phosphate, sand and borax (Genkare) were manufactured. Inves ga on of the radioac vity present in these materials (phosphate rock, cement dust, limestone, sand and borax) enables one to assess any possible radiological hazard to humankind by such materials. Materials and Methods: Fi%een samples were collected from five loca ons. Ac vity measurements have been performed by gamma-ray spectrometer, employing a high-resolu on scin lla on detector NaI (Tl) crystal 3 ×3 inch. In addi on, the radiological hazards were calculated for the inves gated samples. Results: The average values of ac vity ranged from 28± 2 to 163± 12, 2. 8± 0. 7 to 40± 3 and from 49± 4 to 1337± 74 Bq kg-1 for 226R, 232Th and 40K, respec vely. The values of absorbed dose rates, radium equivalent ac vi es and annual effec ve dose due to 226Ra, 232Th and 40K respec vely, are ranged from 22. 05 to 101. 59 nGy h-1, 45. 90 to 224. 22 Bq kg-1 and 27. 04 to 124. 59 μ Sv y-1. In addi on, the values of external hazard index, internal hazard index and gamma index have been calculated. Conclusion: According to the obtained results, all materials would not present a significant radiological hazard except phosphate. The results of the study could serve as important baseline radiometric data for future epidemiological studies and monitoring ini a ves.
