Background: Radiation is a radiation dose rate at a specified location which is generated by any combination of natural and artificial (man-made) ionizing radiation sources. Background radiation varies with location and time. The global average exposure of humans to ionizing radiation is about 2.4 – 3mSv (0.0024-0.003Sv) per year.
Objective: To detect, and calculate the total cumulative dose of radiation exposure in the center of the store and outside by moving the detector " portable PalmRAD" away from a source.
Patients and Methods: By using portable PalmRAD 907 Nuclear Radiation Meter to detect, and calculate the total cumulative dose of radiation exposure in the center of the store and outside by moving the detector " portable PalmRAD" away from a source. the study was conducted in 2015, the first of March up until June.
Results: The findings indicate that approximately 100% of students, academic staff or public in general are exposed to radiation near the store`s window (3.5 m from the store center), and the estimated total cumulative dose of radiation exposure exceeded (13 µ Sv / day) and compare this finding with the standards level of radioactive substances, "Cs137" is (8.333 µ Sv / day) or (3000 µ Sv / year) [5, 18]. It is concluded that there is a risk to any low level radionuclide exposure.
Conclusion: Low-level radiation can cause many health problems; even any level of radiation can be dangerous. There is always a bad effect of natural background radiation on DNA as well as several measures of health.
