In this study, natural radioactivity in samples of rice and pulses from southern Bangladesh's Patuakhali District was assessed. ²²⁶Ra, ²³²Th, and ⁴⁰K activity levels were measured in thirty rice and thirty pulse samples. ⁴⁰K varied between 62 and 125 Bq kg⁻¹ in rice, and 190 to 450 Bq kg⁻¹ in pulses, while ²²⁶Ra and ²³²Th were below detection limits. The gamma index in pulses was slightly higher, but other radiological hazard indices, such as radium equivalent, dose rate, annual effective dose, and lifetime cancer risk, were largely below global limits. The findings offer crucial baseline data for regional environmental radiation monitoring and food safety.
