| Summary: | Radionuclides such as Uranium-238 (238U), Thorium-232 e32Th) and Potassium-40
(40K) are unstable nucleus. It can occur naturally and known as second highest cause
for lung cancer if being exposed for long period of time. UiTM Pahang campus
Jengka is one of the branches of UiTM in Pahang. The study was done to know the
concentration of naturally occurring radioactive material (NORM) in the soil aside
from to find the radiological risk by calculate the external hazard index in UiTM
Pahang. The sample was collected by using hand auger and then survey meter is used
to obtain the absorbed dose rate of that place. Then the soil was dried up in oven at
700C for 24 hr. After being dried up, the soil is then sieved through 355 J.Ul1 sieve. By
using EDXRF, the concentration of 238U, 232Th, 4~ and external hazard index was
. obtained as 45.1 ± 2.9Bq/kg, 59.3 ± 2.9Bq/kg, 447.8 ± 26.7Bq/kg and 0.33 Hex. Then
an isodose map was generated by using Surfer 14 software |
