The harm caused by ionizing radiation is well known and is performed by depositing energy from the radiation source into the irradiated material. Biosystems fight back to maintain their integrity and functions. Doing so requires external help where important supplements are provided to enable the biosystem to challenge destruction done by irradiation in the form of ionization and free radicals. This work investigates the effect of Moringa oleifera leaves extract, MOLE, on two different gamma radiation dose rates’ damages on the biosystem. This is done by estimating physical parameters that belong to dielectric factors, static permittivity, or based upon them as thermodynamic state functions; changes in Helmholtz free energy, internal energy, and entropy of the sample under assessment. Good sensitivity to factors causing changes in the studied system's net dipole moment is noticed, especially within the 1st week. The help of MOLE, a natural supplement, to the biosystem repairing the damage caused by irradiation was tested. Data indicated that MOLE has a powerful influence that could help the biosystem, based on its vast nutrients, trace elements, and antioxidants to fight radiation damage.

Gamma Radiation Dose

Background: In this study, outdoor environmental gamma radiation dose rates were measured at area of Shahbag Thana under Dhaka city and Atomic Energy Research Establishment (AERE) Campus at Savar. Aim of the study: This kind of study is required to detect the presence of natural and artificial radionuclides (if any) releasing from nuclear and radiological facilities in the country or from neighbouring countries. Materials and Methods: The measurement was performed using a real-time portable radiation monitoring device from August-November 2017. The real-time portable radiation monitoring device was placed on tripod at 1 meter above the ground and data acquisition time for each monitoring point (MP) was 1 hour. Total 34 MP were selected around major nuclear and radiological facilities in Bangladesh for collection of dose rate due to gamma-ray. The MPs were marked-out using Global Positioning System (GPS) navigation. The GPS reading of the sampling locations were varied from E90º23'40.08" to E90º24'32.82" and from N23º44'58.62" to N23º43'26.58" for Shahbag Thana and from E90º16'26.58" to E90º16'50.52" and from N23º57'12.96" to N23º57'6.12" for AERE Campus, Savar. Results: The measured dose rates due to natural radionuclides were ranged from 0.105 ± 0.036056 μSv.h-1 to 0.208065 ± 0.106377μSv.h-1 with an average of 0.141568 ± 0.046995 μSv.h-1. The annual effective dose to the population from outdoor environmental gamma radiation was varied from 0.128772 ± 0.044218 mSv to 0.25517 ± 0.130461 mSv and the mean was found to be 0.17362± 0.057635 mSv. This value is lower than some countries like India, China, Sweden, Italy and Czech Republic; and higher than Canada, Mexico, Indonesia, Korea, Turkey, Finland, Spain and some other countries. Conclusion: From this study, it was observed that there is no burden of population exposure due to man-made sources. Therefore, it can be concluded that adequate safety and radiation protection of nuclear & radiological facilities had been ensured which is required for minimizing of unnecessary exposure to populations from man-made sources. The estimated mean annual effective dose found in this study is not expected to contribute significant additional hazard from the radiological health point of view.
