“…These pathways can expose people to high doses of radiation, which can increase the risk of cancer and other health problems 13,14 . Background radiation levels can vary depending on the location, so it is important to have this information in order to assess the potential risks of radiation exposure 15,16 . The levels of radioactivity in soil from these three radionuclides are relatively low, with mean values of 33, 45, and 412 Bq kg −1 , respectively.…”

The study found that the activity concentrations of the radionuclides 238U, 232Th and 40K in the sandstone are 32 ± 13, 29.6 ± 12.2, and 132.6 ± 86.4 Bq kg−1, respectively. These values are lower than the reported worldwide limits of 33, 45, and 412 Bq kg−1. According to the present study, the absorbed dose rate (Dair), the annual effective dose, and the excess life time cancer were all found to be below the worldwide mean. Pearson correlation, PCA, and HCA were used to analyze the data and identify patterns in the relationship between radionuclides and radiological hazards. A statistical analysis of the sandstones showed that the radioactive elements 238U, 232Th and 40K are the main contributors to the radioactive risk. The study suggests that the sandstone is safe to use. The levels of radioactivity are not high enough to pose a risk to human health.

Surface sediment samples were collected from 12 different sites in Manzala Lake for measuring 238U, 226Ra, 232Th and 40K. Those elements were measured using High Purity Germanium (HPGe) detector. The concentrations of radionuclides were within the UNSCEAR limits. Various indices were applied to detect the environmental and human risk assessment for example activity utilization index, external hazard index and others. Environmental Risk from Ionising Contaminants: Assessment and Management (ERICA) tool was applied and showed no considered biological hazards. The results showed that concentrations of radionuclides in sediments of Manzala Lake were within the safe limits for further uses.
