Abstract
Groundwater quality is an important concern for public health, particularly with respect to uranium contami
nation, which may contribute to radiation dose and chemical toxicity when used for drinking. An analysis of
radiation levels in groundwater has been undertaken around Noida, Uttar Pradesh, India, using the LED Fluo
rimetry Technique. The concentration of uranium (U-238) in water samples obtained from submersible pumps,
tube wells, and hand pumps in Noida is determined. The uranium concentration, averaging 10.62
with the annual effective dose of 1.77

, falls within the safety thresholds recommended by the World
Health Organization (2004) and the Atomic Energy Regulatory Board (2004). The chemical toxicity and
radiological impact of uranium in water have been assessed. To estimate radiation risks from natural radionu
clides in groundwater, radiological health parameters were determined. Elevated activity levels of natural ra
dionuclides in certain areas are attributed to factors such as regional geology, hydrology, and the nature of local
industries.
