Accumulation of lead radionuclides in 18 leaf vegetable types in Viet Nam.

Studying the concentration of radioactive lead in soil and plants, and using plants for phytoremediation are important for the environment and human health protection. In this study, we used gamma spectrometry to determine activity concentration in soil - plants, transfer factor. The average activity concentration of lead radionuclides in soil and plants were in the following order of Pb > Pb > Pb.

Estimating the Internal Dose for 131I Production Workers From Air Sampling Method.

Besides the most common methods of internal dose assessment from inhaled 131I, that are thyroid monitoring and urine analysis, air sampling is a possible way but rarely used for dose estimate. This study aimed to focus on the utilisation of portable air sampler to estimate the internal dose for workers working at 131I production facility. In addition, internal dose estimated from urine analysis at the same time was carried out for comparison.

Using smartphone as a motion detector to collect time-microenvironment data for estimating the inhalation dose.

During the production of iodine-131 from neutron irradiated tellurium dioxide by the dry distillation, a considerable amount of (131)I vapor is dispersed to the indoor air. People who routinely work at the production area may result in a significant risk of exposure to chronic intake by inhaled (131)I. This study aims to estimate the inhalation dose for individuals manipulating the (131)I at a radioisotope production.
