The ten most popular vegetables in Vietnamese diet were selected, namely choy sum, crown daisy, lettuce, cabbage, Malabar spinach, beans, sweet potato, potato, kohlrabi and carrot. This is the first study in this area for Vietnamese vegetable samples. To further this goal, the activity concentrations, transfer factors, and radiological hazards of 226 Ra, 232 Th, 40 K, and 137 Cs were studied for ten pairs of selected vegetables and soils in Tien Le near Hanoi in Vietnam. The study of staple food products is crucial to assure public safety and provides input for predictive dose assessment models. Radionuclides (226Ra, 232Th, and 40K) present in these states. Provides data on exhalation rates and activity concentration of natural Pradesh and Uttarakhand are considered for this examination. Punjab, Haryana, Himachal Pradesh, Rajasthan, Uttar Radon levels should be available for further work in this field. To comprehensively report with different techniques all those studies beingĬarried out in this part of India so that a current assessment of the indoor Levels at different locations throughout the world. Has been undertaken by numerous research organizations to determine their Due to these health-related concerns, a lot of work Toxins that, after cigarette smoking, is the second most common cause of Naturally present, contributing to radon and thoron gases in the indoor as The Earth's surface, the radioactive elements uranium and radium are They are major sources of harmful radiation, radionuclides found in theĪtmosphere might result in a substantial potential risk to living beings. Human beings are constantly exposed to radioactivity in the environment. Value reported in the data for tropical plants. Plants, while transfer factor value for 226Ra was 15 times higher than the Type vegetables, showing a similar value in other studies involving tropical Transfer factor value of 40K was greater than 1 found in beans and fruit The acquired results wereĬompared to the levels that are globally recognized as acceptable. Lowest transfer factor value in all vegetables. Radionuclide 40K has the highest transfer factor value in most vegetables,Įspecially in the fruit type vegetable, and 232Th was found to have the The activityĬoncentration ranges for 226Ra, 232Th, and 40K in various vegetable samples
The results showed that the activity concentration ranges forĢ26Ra, 232Th, and 40K in the soil of the vegetable were 2.72-46.54 Bqkg-1,ĩ.01-54.84 Bqkg-1, and 19.22-477.76 Bqkg-1, respectively. Of radionuclides from soil to vegetables obtained from farms in Klang Vegetables and peat soil were investigated to determine the transfer factors
The activity concentrations of naturally occurring radionuclides in
