Due to factors such as convenience, affordability, and ease of preparation, instant noodles have become a staple food worldwide, including in Malaysia. The country boasts a significant instant noodle market, exhibiting high per capita consumption, particularly among students, children, and individuals with busy lifestyles. This study aimed to investigate the concentrations of naturally occurring radioactive materials (NORM) in popular instant noodle brands widely consumed in Malaysia. Samples were collected from the AEON supermarket in Mid Valley Megamall, Kuala Lumpur. The concentration of NORM in the instant noodle samples was assessed using a HPGe gamma-ray spectrometer and found a variation in the activity of radionuclides across different samples. Overall, the activity concentrations (Bq kg−1) of 226Ra, 228Ra, and 40K are in the ranges of 4.2 ± 1.1–15.1 ± 1.9, 1.3 ± 0.3–4.4 ± 0.3, and 54.6 ± 5.3–521.2 ± 26.0, respectively. The annual effective dose was estimated based on the consumption characteristics of instant noodles by the local population and was found to be below the allowed limit of 290 μSv y−1, as suggested by UNSCEAR. Hence, no immediate health risks were identified. Although the sampled noodle brands do not currently pose a significant radiological risk to the public, cumulative dietary exposures over time may not be entirely negligible. This is because the UNSCEAR reference limit considers contributions from all food, i.e., not for a single food item. Therefore, periodic monitoring of radiation levels in instant noodles is recommended to maintain public health and safety.
