Harmful Effects

Dental radiographs have long been the standard method for detecting oral illness. The harmful effects of radiation produced by dental radiographs is very low but still continuous exposure to radiation will cause harm to human health. This study aim is to estimate the awareness of radiation safety and protection in dental practice. Material and method - A questionnaire with ten questions was prepared and circulated to 100 dentists from different parts of India. Responses were gathered, and an appraisal was made as a result. Result- A total of 100 dentists responded enthusiastically and took part in it. Most of the dentists were aware of harmful effects of dental x-ray and its radiation physics and biology. Many of them are not using personal monitoring device for measuring radiation exposure. Conclusion: Radiation security expertise and experience was insufcient. While many participants had strong knowledge of radiation safety, risks, and defense, some fall into the average knowledge group, according to this study. In spite of having knowledge of harmful effects of radiation, many dentists have not used any safety protection and have not followed safety protocols. To avoid the risks in future more awareness programs have to be conducted about radiation safety and protection

Harmful Effects

Modern vascular surgeons perform an ever-increasing number of complex endovascular procedures, largely based on patient preference, decreased length of stay, and improved outcome. With the upsurge of endovascular cases, concern has grown regarding the harmful effects of radiation exposure delivered to the patient and the operator. Surgeon education on the appropriate use of fluoroscopic operating factors coupled with appropriate training in radiation safety has been shown to decrease radiation dose. This review elucidates dose terminology and metrics, possible radiation-induced injuries, risk factors for deterministic injury, and radiation safety principles and techniques. Tables provide practical tips to lower patient and operator radiation dose during fluoroscopically guided intervention, and National Council on Radiation Protection & Measurements recommended dose limits for occupational exposure. Figures illustrate reference air kerma, radiation-induced skin injury, effects of image receptor and table position, and operator exposure. This review contains 4 figures, 3 tables, and 53 references.

Dose Tolerance

An extensive radiation chemistry literature would suggest that the addition of certain radical scavengers might mitigate the effects of radiation damage during protein crystallography diffraction data collection. However, attempts to demonstrate and quantify such an amelioration and its dose dependence have not yielded consistent results, either at room temperature (RT) or 100 K. Here the information thus far available is summarized and reasons for this lack of quantitative success are identified. Firstly, several different metrics have been used to monitor and quantify the rate of damage, and, as shown here, these can give results which are in conflict regarding scavenger efficacy. In addition, significant variation in results from data collected from crystals treated in nominally the same way has been observed. Secondly, typical crystallization conditions contain substantial concentrations of chemical species which already interact strongly with some of the X-ray-induced radicals that the added scavengers are intended to intercept. These interactions are probed here by the complementary technique of on-line microspectrophotometry carried out on solutions and crystals held both at 100 K and RT, the latter enabled by the use of a beamline-mounted humidifying device. With the help of computational chemistry, attempts are made to assign some of the characteristic spectral features observed experimentally. A further source of uncertainty undoubtedly lies in the challenge of reliably measuring the parameters necessary for the accurate calculation of the absorbed dose (e.g.crystal size and shape, beam profile) and its distribution within the volume of the crystal (an issue addressed in detail in another article in this issue). While microspectrophotometry reveals that the production of various species can be quenched by the addition of scavengers, it is less clear that this observation can be translated into a significant gain in crystal dose tolerance for macromolecular crystallographers.

Effects Of Radiation

Radiation damage is the general curse of structural biologists who use synchrotron small-angle X-ray scattering (SAXS) to investigate biological macromolecules in solution. The EMBL-P12 biological SAXS beamline located at the PETRAIII storage ring (DESY, Hamburg, Germany) caters to an extensive user community who integrate SAXS into their diverse structural biology programs. The high brilliance of the beamline [5.1 × 1012 photons s−1, 10 keV, 500 (H) µm × 250 (V) µm beam size at the sample position], combined with automated sample handling and data acquisition protocols, enable the high-throughput structural characterization of macromolecules in solution. However, considering the often-significant resources users invest to prepare samples, it is crucial that simple and effective protocols are in place to limit the effects of radiation damage once it has been detected. Here various practical approaches are evaluated that users can implement to limit radiation damage at the P12 beamline to maximize the chances of collecting quality data from radiation sensitive samples.

Short Period

One of the fundamental quests of nuclear cardiology is the search for elements with appropriate chemical properties for use in radiopharmaceuticals, which have radioactive isotopes that produce photons well suited for imaging, and deliver only a small radiation dose to the patient. This requires that that the emission of any radiation that does not contribute to the image be kept to a minimum and that the isotope remains radioactive only for a short period of time. Understanding the emission of radiation from atoms requires an understanding of atomic and nuclear structure and forces.
