RADIOACTIVE ACTIVITIES IN PLANT IN THE AREA THE RARE EARTH MINE MUONG HUM, LAO CAI

Content

1. Introduction Currently, the study of using plants as indicators in environmental monitoring, evaluation and treatment has been widely applied in the world. Because indicator plants are closely related to the living environment, they are also an important link in the transport of radionuclides from the source of pollution to humans and can be used as a method. environmental treatment techniques [1-3]. Therefore, in recent years, the method of using plants to treat radioactive pollution has been interested in research and investment because of its low investment cost, safety and environmental friendliness [4-6]. In the process of growth and development, plants absorb natural or artificial radioisotopes in the surrounding environment, especially in areas containing high levels of radionuclides. Therefore, in plants, there is a certain amount of radionuclides, and depending on the high or low radioactive content, the long or short use time of the plant will directly affect human health. Therefore, the determination of total alpha and beta activities in plant samples has been studied recently by domestic and foreign scientists [6-10]. The article presents the results of determining alpha and beta radioactivity in plant samples taken in the area of ​​Muong Hum commune, Bat Xat district, Lao Cai province. This is an area of ​​rare earth mines containing natural radionuclides with high concentration. 2. Research Methods 2.1. Research subjects In this study, the author selected to conduct with 04 types of samples as follows: 03 samples of morning glory; 04 samples of cruciferous vegetables; 02 samples of beans and 02 samples of potatoes. These are samples grown and used by people in the area every day. +) Water spinach: Water spinach contains many substances that are very important for the living organism such as: protit, glucose, cellulose. On the other hand, water spinach has good ability to absorb heavy metals, radiation, toxic substances... in water and soil. +) Vegetables contain many substances such as protein, glucose, fiber, vitamins, minerals such as calcium, potassium, sodium, phosphorus ... Vegetables also have the ability to absorb toxic substances, heavy metals, radioactive substances. uranium, radium… +) Cowpea contains protein, vitamins A and C, many vitamins of group B and many important trace elements for the body\'s development such as calcium, iron, potassium, phosphorus, magnesium, zinc... +) Potatoes: Potatoes contain a lot of starch, many B vitamins and minerals necessary for humans such as zinc, calcium, magnesium, iron, phosphorus ... Samples of morning glory, vegetables, cowpeas, potatoes were collected in the vegetable growing area of households in Muong Hum commune, these are the foods commonly consumed by people in the area. 2.2. Research Methods In this work, the author has selected the method of processing and processing samples according to the ashing method. The advantage of this method is that it avoids chromogenic reactions that increase the “Quenching” effect in the detector and has high sample recovery. The disadvantage of the method is that it requires specialized skills and equipment. The treatment of samples by the ashing method is depicted in Figure 1 [6-10]. Figure 1. Sample processing diagram

3. Sample treatment

• Samples of green vegetables were removed from the root, withered leaves, then washed with water, rinsed with distilled water twice, and left to dry at room temperature;
• ; Potato samples were washed, peeled and allowed to dry at room temperature;
