This study investigates radioactivity in the ambient air for a district in Hanoi capital, Vietnam, in the period 2015 - 2018. Aerosol samples are collected by Taifful (Тайфун, Russia) equipment, using ΦПП 15-3p filter, to determine the 40K, 238U, and 232Th concentration by gamma spectrometry method and following the STI/DOC 010/295 TRS 295-IAEA-1989 guidelines. |
