Sardar Q A D E R Othman
I am Sardar Qader Othman Qader, lecturer of medical physics at Erbil Polytechnic University, Erbil Technical Health and Medical College.
I am graduated from the College of Science, University of Salahaddin in 2010-2011, then after I awarded an MSC. Degree in Biophysics from the Physics Department College of Science, University of Salahaddin since 2015- 2017 and then pointed as an assistant lecturer at Erbil Polytechnic University.
I was awarded a PhD from Salahaddin University – Iraq in "2020-2023" for work in Physics, Medical Physics "Health Effects and Radiological Risk Assessment of Radon Inhalation on Workers of Building Material Factories in Erbil City Using Radon Lung Dosimetry Models ".
During my academic life, I have taught, the following subjects for undergraduate students: Nuclear Lab in the fourth stage at the Physics department, and physical therapy intervention, in the second stage at the Physiotherapy department.
I have participated in many international and local conferences and I published many scientific articles. My current research interests include Nuclear radiation, medical physics, radiation physics, and Radiological protection.
I was a member of:
1) Kurdistan Teachers Union since 2011.
2) Kurdistan Physicists' Syndicate since 2011.

materials is required for estimating the interior and
exterior exposure to ionizing radiation emitted by terrestrial radioactive elements in building materials.
Using gamma-ray spectroscopy, the activity concentrations of 226Ra, 232Th, and 40 K in ffty-two samples
from eighteen diferent building materials commonly
used in Erbil city, Kurdistan region, Iraq, were evaluated to assess possible radioactive dangers to human
health. The activity concentrations of 226Ra, 232Th and
40 K ranged from 1±0.1 (gypsum board) to 130±11
(granite), 1.3±0.2 (gypsum) to 66±8 (ceramic sample), and 18.74±4 (gypsum) to 1061.708±40 (granite) with an average of 28±5, 20.7±4, and 340.8±18
(average±standard deviation), respectively. Radiological indicators (activity concentration index, alpha
and gamma index, hazard indices, interior absorbed
gamma dose rate and the corresponding yearly efective dosage rate, and excess lifetime cancer risk) were
computed to assess the health risks associated with these building materials. Consideration was given to
the indoor annual efective dosage for common construction materials, the radon surface expiration rate,
and the indoor radon concentration. The mean values
of activity concentration were then inputted into the
RESRAD-BUILD computer software to calculate a
resident’s long-term radiation exposure. The dosages
were measured over a range of 0 to 70 years. From
0 to 30 years, there was a signifcant change in dosages; however, from 30 to 70 years, the dosages were
reasonably consistent. This research demonstrates
that granite samples are not safe for dwellings with
poor ventilation (especially those without windows).
In general, other investigated construction materials
in the buildings are deemed safe for the population,
since the computed values for these parameters fall
within the well-being restrictions or criterion values.
