Abstract
Nowadays, the determination of the total content of radioactive substances contained in plants is a great concern of public health care and in radiation safety control. However, the radioactivity in this type of sample is often very low, making their determination very difficult. This paper presents a method to determine the total alpha and beta radioactivity in plants by the HPGe gamma spectrometer and the LB4200 total alpha and beta measurement system at the laboratory of the Institute of Nuclear Science and Technology, the Institute of Energy. Vietnamese atom. Analytical results of 10 plant samples (04 samples of vegetables, 03 samples of water spinach, 02 samples of beans, 02 samples of potatoes) collected from households growing in the area of rare earth mine Muong Hum, Bat Xat district, Lao Cai province showed a clear distinction between plant samples, total alpha activity in tubers and fruit samples was higher than in green vegetable samples; The total beta activity in the samples was very low, almost negligible.
