BACKGROUND The use of computed tomography in Israel has been growing rapidly during recent decades. The major drawback of this important technology is the exposure to ionizing radiation, especially among children who have increased organ radiosensitivity and a long lifetime to potentially develop radiation-related cancer. OBJECTIVE To estimate the number of excess lifetime cancer deaths relat...

This article shows the development of an instrument for measuring exposure parameters used to take radiographic studies in living beings; such as kilovoltage, current and time, since radiation protection is a fundamental pillar care patients operators ionizing equipment, it necessary calibrate these equipment that produce X-rays. For manufacture ESP32 microcontroller which programmed using Pyth...

Introduction Ionizing radiation comes from natural (radioactivity and cosmic radiation) or artificial sources. The ionizing radiation, which includes the X-ray radioactive isotopes produced in nuclear reactors, has many applications, notably industries, investigation medicine sectors, turning health professionals into exposed workers. Case description A case of a 61-year-old women, radiologic t...

background: medical x-rays are the largest man-made source of public exposure to ionizing radiation. it is important to avoid conditions where the amount of radiation used is more than that needed for the procedure. materials and methods: the entrance skin exposure (ese) measurement was conducted for quality control of x-ray machines and survey of operator’s experimental techniques. the eses we...

In this study, we have evaluated the interactions between ionizing radiation and a matrix metalloproteinase (MMP) inhibitor. Using Matrigel invasion assays, we show that ionizing radiation induced a dose-dependent increase in the invasive phenotype of cultured B16 melanoma cells and that conditioned medium from these irradiated B16 cells promoted endothelial cell [human microvascular endothelia...

BACKGROUND Invasive and noninvasive cardiovascular imaging is beneficial in the care of patients admitted with acute myocardial infarction. Little is known about patients' cumulative radiation exposure. METHODS AND RESULTS All patients admitted with an acute myocardial infarction to any of 49 University HealthSystem Consortium member hospitals from 2006 to 2009 were reviewed for inpatient pro...

Background—Invasive and noninvasive cardiovascular imaging is beneficial in the care of patients admitted with acute myocardial infarction. Little is known about patients’ cumulative radiation exposure. Methods and Results—All patients admitted with an acute myocardial infarction to any of 49 University HealthSystem Consortium member hospitals from 2006 to 2009 were reviewed for inpatient proce...

In this paper, we report on ultra-low power consuming single poly floating gate direct radiation sensors. The developed devices are intended for total ionizing dose (TID) measurements and fabricated in a standard CMOS process flow. Sensor design and operation is discussed in detail. Original array sensors were suggested and fabricated that allowed high statistical significance of the radiation ...

Ionizing radiation is a potent carcinogen, inducing cancer through DNA damage. The signatures of mutations arising in human tissues following in vivo exposure to ionizing radiation have not been documented. Here, we searched for signatures of ionizing radiation in 12 radiation-associated second malignancies of different tumour types. Two signatures of somatic mutation characterize ionizing radi...
