A 512 512 CMOS active pixel sensor (APS) was designed and fabricated in a standard 0.5m technology. The radiation tolerance of the sensor has been evaluated with Co-60 and proton irradiation with proton energies ranging from 11.7 to 59 MeV. The most pronounced radiation effect is the increase of the dark current. However, the total ionizing dose-induced dark current increase is orders of magnit...

BACKGROUND The incidence rates of differentiated thyroid cancers of all sizes increased between 1988 and 2005 in both men and women. Exposure to ionizing radiation is the best-established environmental risk factor for thyroid cancer. Nonionizing radiation from cell phones has also been implicated. A positive correlation between all-cancer incidence rates and latitude and an inverse correlation ...

High frequency nonionizing electromagnetic fields (HF-EMF) that are increasingly present in the environment constitute a genuine environmental stimulus able to evoke specific responses in plants that share many similarities with those observed after a stressful treatment. Plants constitute an outstanding model to study such interactions since their architecture (high surface area to volume rati...

Aims and objectives: To find out the frequency of splenomegaly in patients with abdominal ultrasound Methods: This prospective cross-sectional study was conducted at Radiology Department City Care Hospital Gujranwala. A total 65 participants pain left upper quadrant were included study. Patients ranged age from 21 to 75 years old, 37 men 28 females. Statistical analysis then performed using SPS...

Current research indicates a role for several oncogenes in radiation-induced carcinogenesis in vivo and cell transformation in vitro. Certain oncogenes are probably also involved in some cases of human cancer caused by exposure to nonionizing radiation and may play a mechanistic role in the phenomenon of radioresistance seen in later stages of tumor progression. The mechanisms of oncogene activ...

Radiation is the transmission of energy through space and matter. There are several forms of radiation, including ionizing and nonionizing. X-rays are the ionizing radiation used extensively in medical and dental practice. Even though they provide useful information and aid in diagnosis, they also have the potential to cause harmful effects. In dentistry, it is mainly used for diagnostic purpos...

People are continuously exposed to radiation emitted by the natural and man-made sources. Exposures to ionizing and to nonionizing radiation are known to impact human health. Effects exerted by any type of radiation might be potentiated by coexposures to other types of radiation as well as by co-exposures to chemicals and other environmental pollutants. Inherent individual sensitivity of person...

Ionizing radiations deposit a wide range of energies in and around DNA and this leads to a corresponding spectrum of complexity of the lesions induced. The relationships between the amount of energy deposited and the yields and types of damage induced are important in modelling the physical and chemical stages of radiation effect and linking them to biological outcome. To study these relationsh...
