Detecting some residential areas with high radioactivity

According to information from the Federation of Geological and Radiation rare, currently some areas of natural radiation in Vietnam have many people living. The danger is that these areas have a higher level of radioactivity than permissible environmental standards.

Talking to reporters on June 30, Mr. Tran Binh Trong, Deputy Head of Technical Division of the Federation, said that some natural radioactive areas such as Tien An commune (Tien Phuoc district, Quang Nam) have many people born. living. Especially, people here use graphite ore wells containing uranium.

In addition, there is a rare area of ​​Nam Xe (Lai Chau), Binh Duong (Cao Bang), Southeast Ben Giang (Quang Nam) and Muong Hum rare earth mine (Bat Xat district, Lao Cai). In Muong Hum, people use land containing radioactive elements to build walls.

According to Mr. Trong, the accumulation of radiation energy in one year in these regions is usually at 2-4mSV. Meanwhile, according to Vietnamese environmental standards, if the radiation energy accumulation in a year exceeds 1mSV, it is considered unsafe for people.

It is known that the above areas are the areas surrounding radioactive mines and radioactive mines. And radioactive mines and radioactive mines have been delineated and protected.

Trong also said that when radioactive elements are dispersed into water, plants, air ., they penetrate into the body through breathing and eating, causing a dose of radiation in danger. In other words, radioactive elements decay in the body, destroy or alter tissue, lead to cancer, cause genetic mutations, teratogenicity or malformations for the irradiated children. If exposed to external radiation (radiation from outside the environment exposed to the body) can cause white blood disease .

In this regard, VietNamNet correspondent contacted Mr. Ngo Dang Nhan, Director of the Department of Radiation Safety and Control, via mobile phone in the afternoon and evening of July 2, but Mr. Nhan did not pick up the phone.
