Radon exhalation rate and natural radioactivity in the building materials used in metropolitan Jakarta and its surrounding areas, Indonesia.

ABSTRACT:

Introduction

Creating a safe living environment involves using healthy and sustainable building materials. Humans are exposed to natural radionuclides, such as ²²⁶Ra, ²³²Th, and ⁴⁰K decay series, found in building materials that pose a radiological hazard. This study is aimed to investigate the radionuclides content of building materials used in Jakarta and its surrounding areas. The computer code RESRAD-BUILD was used to calculate the annual effective dose received by an adult living in a typical room constructed with the studied building materials.

Methods

Samples such as sand, cement, bricks, and Autoclaved Aerated Concrete (AAC) were collected. The ²²²Rn surface exhalation rate was determined using the closed chamber method usi
