Trace element analysis by multiple gamma ray detection method
We have developed a new analytical method of NAAMG
by combining INAA and multiple gamma ray detection
method. The multiple gamma ray detection method is widely
used in the field of the nuclear physics. The advantages of...
Modeling an HPGe detector response to gamma-rays using MCNP5 code
extracted a set of correction factors to take into account the gamma ray self-absorption within the source volume. The simulated model of the HPGe detector in this study can be used to calculate the detection efficiency when the samples...
The source altitude, electric current, and intrinsic brightness of terrestrial gamma ray flashes

The daily radon dose in body organs caused by drinking milk and water
water could be the main cause of its presence in milk. Different portion of milk changed by radon gamma ray and consumption of radon included water
or milk has its effects on the human body. For investigation the effect of radon in water or milk...
Effect of low dose gamma ray on the plasmonic behavior of gold nanoparticle
The aim of this paper is to study the effect of very low dose gamma radiation exposure on the plasmonic behavior of gold nanoparticles. For this purpose, gold nanoparticles were exposed to three different dose rates of ...
Use of gamma-rays back scattering of the 192Ir isotopic source for the design of the landmine detection device
In our previous work [1], the detector collimator of the landmine detection device has designed and optimized using gamma-rays back scattering of 241Am isotopic source with 0.06 MeV in energy and NaI(Tl) detector. In this study the effect...
Aptamers Can Monitor Ionization Radiation
Ionization radiation, even at low doses, causes various diseases and is one of the main reasons for many kinds of cancers. Therefore, the detection and control of low doses of ionizing radiation are very important in nuclear ...
Study of Existing Radon In Milk and Its Effect on Body Organs
in two phases with use of MCNPX software. In the first phase , the dose rate of absorbed gamma ray by components of milk which is indoctrinated by 1Bq/m3 of Radon during a day, is calculated at (nrad). In the second phase as well, according to the human...
