Abstract The present work introduces an open-source graphical user interface (GUI) computer program called DynamicMC. has the ability to generate ORNL phantom input script for Monte Carlo N-Particle (MCNP) package. relative dynamic movement of radiation source with respect can be modeled, which essentially resembles source-to-target (i.e., human phantom) distance in a 3-dimensional field. makes organ-based dosimetry body much easier, as users are not required write lengthy scripts or deal...
Abstract Previously, we have developed DynamicMC for modeling relative movement of Oak Ridge National Laboratory phantom in a radiation field the Monte Carlo N-Particle package (Health Physics. 2023,124(4):301–309). Using this software, three-dimensional dose distributions irradiated by certain mono-energetic (Mono E) source can be deduced through its graphical user interface. In study, extended to used combination with Particle and Heavy Ion Transport code System (PHITS) providing it higher...
This study investigates the presence of radionuclides in soil, plant, and milk samples from rural urban areas. Using gamma spectrometry, activity concentrations were measured to assess potential exposure pathways for external radiation radionuclide transfer through food chain. Higher levels generally observed environments, while certain plant revealed trace contamination. These findings underscore importance continuous environmental monitoring safeguard safety mitigate risks associated with...
The FOTELP-VOX program is a Monte Carlo simulation tool designed for precise radiation dose calculations in medical physics. It allows the accurate modeling of photon, electron, and positron transport through human tissues by using CT scan data to define patient anatomy. This study presents application simulating absorbed distributions various clinical scenarios, including radiotherapy treatment planning salivary gland tumors, eye melanoma breast cancer. results demonstrate program's...
In the present work, we determined activity concentrations of ten Medicinal herbs using gamma spectrometry. The radioactivity concentration 226 Ra, 232 Th, 40 K and 137 Cs were 2.82, 0.63, 984.32, 0.28 Bq/kg, respectively. These doses are not hazardous to general public's health. mean values radium equivalent (Raeq), absorbed dose rates (D), annual effective (De) external hazard index (Hex) 79.51 42.73 nGy-1 , 52.40 µSv 0.21, plants used make tea do contain a tested radionuclides that would...
This paper illustrates the potential of FOTELP-VOX code, a modification general-purpose FOTELP combining Monte Carlo techniques to simulate particle transportation from an external source through internal organs, resulting in 3-D absorbed dose distribution. The study shows comparison results obtained by software and volumetric modulated arc therapy technique. planning technique with two full arcs was applied, plan created destroy diseased tissue eye tumor bed avoid damage surrounding healthy...
Introduction: Non-carious tooth substances loss pose a major health problem of modern man. The literature often collectively describes all non-carious lesions and is therefore difficult to compare results obtained by different authors. Chemical factors are one the predisposing responsible for formation wedge-shaped erosions. Aim: Examination chemical risk as causes lesions. Method: We examined 62 patients with erosions (mean age 45.52 ± 12.03 years, 58.1% men) 60 without in control group...
Boron neutron capture therapy is based on by 10B and creation of high energy alpha particle recoiled 7Li ion which have ranges comparable to cell dimensions. The MCNP5/X code applied for calculation the absorbed doses as well dose distribution depth in pancreas cancer organs analytical voxelized Oak Ridge National Laboratory phantom, represents human body. distributions thermal, epithermal neutrons, spectrum, show that are largest exactly cancer, all cases. It found this simulation neutrons...
Cisplatin is currently used in the treatment of numerous types tumors, such as head and neck, esophagus, bladder, testicle. However, cisplatin use limited due to its cytotoxic effects. Thus, considering side effects, lines research are looking for new technologies reduce dose chemotherapeutic agent needed control disease, which may these The objective this work was perform internal dosimetry 191Pt radioisotope derived from activation natural cisplatin, thus contributing evaluation...
Noise is every unwanted sound, noise appearance (bobbery, murmur, roisterer, banging, speech, etc..) that interferes with work or rest. Physical education characterized by diversity of content, constant change intensity, but teaching process also followed a large number students, health and sanitation terms, micro-climate noise, which are allocated as disturbing factors. This research deals the origin level during implementation series physical classes in elementary schools city Nis. We...
Examination of radioactivity in edible liquids is very important because large amounts are taken into the body during day. This scientific paper presents a comprehensive study on gamma spectrometry analysis and health risk assessment liquids. The involved samples various liquid products such as alcoholic beverages, juices, milk. Milk an part our regular diet for everyone, from newborns to adults, so we determined active concentrations radionuclides both milk farms directly bought...
As mobile phones have become a necessity in modern society, and there is an increasing number of users various ages, it imperative to investigate the impact phone radiofrequency electromagnetic radiation (RF) on humans. Because human head one most exposed sensitive organs body, this paper investigated propagation (EM) field through it. Additionally, Specific absorption rate (SAR) was examined study how RF affects head. A program code using finite-difference time-domain (FDTD) method created...
This study aimed to investigate the presence and activity concentrations of natural radionuclides cesium in soil samples collected from Zlatibor region. A total ten were various locations across area. The analysis was performed using gamma spectrometry measure 226Ra, 232Th, 40K, 137Cs. Additionally, 137Cs found big amounts some samples, indicating its dispersion environment. detected calculated, their potential radiological implications assessed. obtained data this contributes baseline...
Brachytherapy is an integral part of the treatment cervical cancer. In brachytherapy, dose delivered to tissue determined primarily by inverse square law thus decreases rapidly as distance from source increases. Therefore, important role in distribution geometry applicator. A patient’s anatomy well fact that patient may have been operated on must also be taken into account when selecting The aim this study was assess influence type cancer brachytherapy applicators (tandem and ovoids or...
