In order to prevent workers exposed to radiation and comply with the legal requirements set out in Presidential Decree 12/12, of 25 January, the Sociedade Mineira de Catoca acquired more than six hundred dosimeters to prevent those who worked in areas considered to be at high risk.
In an interview with the Internal Channel, the Official Radioprotection Supervisor, Vunge Catalahari, stated that the implementation of sophisticated TLD Panasonic dosimeters, model UD 802 AT, meets the requirements recommended by the National Atomic Energy Regulatory Agency that determines the amount of radiation exposed workers.
"The law stipulates that workers who, due to the nature of their work activities, are exposed to radiation should only catch 10 sievert´s and 80 a day", he stressed. If the data go beyond the figure, he continued, “we will be incurring the illegality” that could be held responsible by the regulatory authority.
The official also informed that more than 600 dosimeters have been available since the second half of August, to be distributed, in the first phase, to the Metallurgy, Assessment, Geology and Corporate Security Departments, considered areas of high risk due to scanners, x-ray separators, among other sources that generate radiation.
In order to achieve the objectives set by the Organization's Radioprotection Committee, Vunge Catalahari said that they are promoting actions to raise awareness of the correct use of the devices.
“A dosimeter is a device whose function is to measure an individual's exposure to radiation over a period of time. It is for personal and non-transferable use, it must be placed close to the chest and at the end of the toil, leave the exit to the radioprotection technician ”, he stressed.
According to Angolan legislation, personal dosimeters are quarterly. At the end of the period, they must be handed over to the regulatory authority to read the respective reports using specific technologies and methods.
