Sádecká J. (2007): Irradiation of spices – a review. Czech J. Food Sci., 25: 231–242. Food irradiation is a process of exposing food to ionising radiation such as gamma rays emitted from the radioisotopes 60Co and 137Cs, or high energy electrons and X-rays produced by machine sources. The use of ionising radiation to destroy harmful biological organisms in food is considered a safe, well proven...

A safe and novel method of detection of bone fracture using ultrasound images is envisaged and presented. Presently Xrays, computed tomography (CT) and magnetic resonance imaging (MRI) are used for bone fracture detection. However, these techniques use ionizing radiation, which is harmful for both patients and medical practitioners. An alternative method for bone fracture detection which is saf...

This paper investigates how much solar UV protection is provided by the shade of Australian trees and the anatomical distribution of personal UV exposures in the shade of these trees. Personal UV exposures in tree shade are of a high enough value to require additional UV reduction strategies. A well planned strategy using a combination of protective methods can minimize the level of exposure to...

Priority setting in radiation policy is complex because it depends to a large extent on risk perception. It has been shown repeatedly that the public is much more sensitive to potential harmful sequelae of radiation than to those of other environmental pollutants. Thus, cancer risk, particularly at low doses, has become a sociopolitical issue. The principle that radiation causes cancer, is life...

Media reports of deaths and devastation produced by atomic bombs convinced people around the world that all ionizing radiation is harmful. This concentrated attention on fear of miniscule doses of radiation. Soon the linear no threshold (LNT) paradigm was converted into laws. Scientifically valid information about the health benefits from low dose irradiation was ignored. Here are studies which...

The number of computed tomography (CT) scans being done for children all over the world is on the rise ever since the advent of Multi-Detector CT (MDCT). However, CT is a potential source of harmful ionizing radiation, and children are more susceptible to its adverse effects. It is essential for the pediatrician as well as the radiologist to be aware of some important principles and guidelines,...

In this review, we discuss the importance of biological and artificial photoprotection against overexposure to harmful ultraviolet radiation. Transient electronic and transient vibrational absorption spectroscopies are highlighted as important tools in understanding the energy transfer in small molecules, with a focus on the application to commercial sunscreens with representative examples give...

This disrupts the vital functions of the skin, which include:  Acting as a physical barrier for the body against mechanical and thermal injury, and hazardous substances  Helping to regulate the loss of moisture  Offering a degree of protection from the harmful effects of ultraviolet (UV) radiation  Providing sensory and autonomic functions, i.e. touch  Regulating body temperature  Acting ...
