Ionizing radiations are commonly used in several sectors in Madagascar, especially in industrial field which represents a significant number of exposed workers. To protect workers against the harmful effect of ionizing radiations, all workers are covered by a personal monitoring program. This study was carried out at the Dosimetry and Radioprotection Department of the National Institute of Nuclear Sciences and Technologies (INSTN-Madagascar) to determine the average annual equivalent doses received by workers in industrial facilities and practices using TLD dosimeters over the last 10 years. The HARSHAW 6600 reader and TLDs cards, type-100 dosimeter cards were used. For this study, only annual doses below the regulatory limits [20 mSv.y-1 for Hp(10) and 500 mSv.y-1 for Hp(0.07)] were taken into consideration during this study. On average, 450 workers from approximately 12 industrial facilities were monitored during this period. The number of workers in 2013 (562 workers) was the highest, when compared to other years. The Hp (10) and Hp (0.07) annual equivalent doses received by industrial facilities over the last 10 years vary respectively from (0.97 ± 0.18) mSv.y-1 to (1.99 ± 0,92) mSv.y-1 with an average value of (1.36 ± 0.57) mSv.y-1, and from (0.96 ± 0.16) mSv.y-1 to (2.03 ± 0.92) mSv.y-1 with an average value of (1.37 ± 0.56) mSv.y-1. It has been established that the industrial radiography practice has received the highest annual doses, it varies from (0.73 ± 0.11) mSv.y-1 to (3.59 ± 2.88) mSv.y-1 with an average value of (1.71 ± 0.99) mSv.y-1 for Hp (10), and from (0.70 ± 0.29) mSv.y-1 to (3.60) ± 2.83) mSv.y-1 with an average value of (1.72 ± 0.99) mSv.y-1 for Hp (0.07).
