“…The penetrating power of gamma rays is so great and stopping it needs the use of perfect shielding material of highly absorption mass co-efficient (Elregig and et al 2020;Matthews 2019;Kars 2019;Subramanian 2020). Laser is artificial electromagnetic radiation that can be obtained with a certain frequency from different laser sources (Gupta and et al 2022;Otsuji and et al 2022;Mahamood and Akinlabi 2021;Webb and et al 2020).The laser may have a high energy density, allowing it to be utilized as a focused laser in surgery or for Low-Level Laser therapy (Mahamood and Akinlabi 2021;Webb and et al 2020;Zhu and et al 2020;Sommer 2019;Stoica 2020;Goswami and et al 2020).…”

The Nyquist plots of female and male DNA Samples were recorded using electrical impedance spectroscopy. The recorded curves were of the same features. The peak of each curve and its half-width were increased and shifted to higher impedance component values as, the expresser time increased 0,5,10,15,20,25 and 30 min, under the effect of any of laser radiation or gamma radiation. The obtained results for the female healthy DNA samples were: The electrical resistance was increased from 346.11KΩ to 922.4KΩ, while the electric capacity was increased from 15.3µF to 24.6µFunder the effect of laser radiation of constantPower100mW, (ℷ=532nm).These results under the effect of gamma radiation were the increase of the electric resistance from 145.37KΩ to 161.45KΩ and the increase of the electric capacity from 9.5µFto 14.1µF. For the male healthy DNA samples, the obtained results were: The electric resistance increased from 140.12KΩ to 929.17KΩ, while the electric capacity was increased from 2.02µF to 7.10µF. This means that the DNA efficiency of the female samples decreased more than that of the male samples. The effect of cement dust on female and male healthy DNA Samples was studied. The selected cement dust concentrations were 0, 1, 2, 3, and 4µL. The results of the DNA female samples were anincreasein the electrical resistance from 131.30KΩ to 2853.34KΩand the increase of the electric capacity from 7.86µF to 71.4µF. The obtained results of the DNA healthy male, samples were the increase of the electric resistance from 583.07KΩ to 4440KΩ and the electric capacity from 19.9µFto 4.82µF. These results confirm the decrease of the female DNA efficiency as a result of the increase of the cement dust concentration, more than that of the DNA male sample .
