Terrestrial gamma radiation dose rate in Cienfuegos, Cuba
This study assesses the level of background radiation for Cienfuegos Province, Cuba.
Measurements of outdoor gamma radiation (of terrestrial and cosmic origin) in air were
performed at 198 locations using a GPS navigator and a dose meter (SRP-68-01,
30 Ă 25 mm NaI detector).
The average absorbed dose was found to be 73.9 nGyâh-1 (17.2â293.9 nGy
h-1),
corresponding to an annual effective dose of 74.7 ÎŒSv (21â324 ÎŒSv). When compared with
the data available for other places, the absorbed gamma doses obtained in this study
indicate a background radiation level that falls within natural limits for the Damuji,
Salado and Caonao watersheds; however, the Arimao and Gavilanes watersheds present levels
of the absorbed dose and annual effective dose comparable with high background radiation
areas. An isodose map of the terrestrial gamma dose rate in Cienfuegos was drawn using the
GIS application âArc Viewâ. This study provides important baseline data of radiation
exposure in the area
