Determination of Radioactivity Concentration and Assessment of Absorbed Effective Dose of Edible Plant and Soil Samples

Autor: Mohammed Elywa

Publikováno v: Arab Journal of Nuclear Sciences and Applications. 52:56-63

The aim of this study is the determination of radioactivity concentrations of naturally occurring of K-40, U-238, and Th-232 and assessment of annulling effective dose of edible plant and its soil samples. The activity concentrations in soil and plan

Dosimetric Evaluation of the Field-in-Field Technique for Large Breast Cancer Irradiation

Autor: Shaimaa Elnabawy, Mohammed Elywa

Publikováno v: Arab Journal of Nuclear Sciences and Applications. :1-11

The aim of this work is using multi-segmented conformal radiotherapy, field in field (FIF) for large breast cancer treatment, the dose coverage of the planning target volume (PTV) and evaluation the radiation load on the organs at risk (OARs). Ten pa

A Comparative Study of Volumetric Brain Tumor Measurements Using Different Manual Methods

Autor: Mohammed Elywa

Publikováno v: Arab Journal of Nuclear Sciences and Applications. 51:51-57

EARLY detection of a minor tumor size change is difficult using traditional visual and clinical examination measurements. Although they are time-consuming, the general manual methods are the standard approach for quantitative measurement of human tum

Estimation of Surface Skin Dose Using TPS and TLD of Breast Radiotherapy Using Co-60 Teletherapy Unit

Autor: Basma El-okba, Mohammed Elywa, Magda Hanfy, Mohamad Abd Elgawad

Publikováno v: Arab Journal of Nuclear Sciences and Applications.

Estimation of surface skin dose is very important for patients who undergo breast radiotherapy to show that the skin dose is under the safe level and to avoid tumor recurrence. The aim of this study is utilizing the thermolumiscent dosimeters (TLDs)
