Radiation Dosage

- A digital electrometer.

- Analytic approximation of the dose distribution from a 6 MeV linear accelerator.

- Breast thickness in routine mammograms: effect on image quality and radiation dose. OBJECTIVE. The purpose of this study was to compare the thickness of the compressed breast between mediolateral oblique and craniocaudal mammograms and to...

- Cell cycle alteration, apoptosis and response of leukemic cell lines to gamma radiation with high- and low-dose rate. The aim of this work was to compare the effect of gamma radiation with sub-low dose-rate 1.8 mGy/min (SLDR), low dose-rate 3.9 mGy/min (LDR) and high...

- Determining the repair rate for radiation-induced chromatid deletions during the first 24 hours after irradiation. The number of chromatid plus isochromatid deletions present in the testes and bone marrow of the Chinese hamster was measured as a function of time following...

- Early morphological changes following gamma irradiation. A comparison of human pituitary tumours and human acoustic neurinomas (schwannomas). The in vitro system was used to study early ultrastructural effects following gamma irradiation of human pituitary adenomas and neurinomas with 30 and 70 Gy...

- Effects of heavy ions and energetic protons on normal human fibroblasts. At the low particle fluences of radiation to which astronauts are exposed in space, "non-targeted" effects such as the bystander response may have increased...

- Effects of weak, low-frequency pulsed electromagnetic fields (BEMER type) on gene expression of human mesenchymal stem cells and chondrocytes: an in vitro study. In vitro effects of electromagnetic fields appear to be related to the type of electromagnetic field applied. Previously, we showed that human osteoblasts...

- Estimation and minimization of fetal absorbed dose: data from common radiographic examinations. A simple method of estimating fetal absorbed dose from common abdominal and pelvic radiographic examinations is presented. The method uses experimentally...

- Estimation of the absorbed dose in radiation-processed food--2. Test of the EPR response function by an exponential fitting analysis. The use of electron paramagnetic resonance spectroscopy to accurately evaluate the absorbed dose to radiation-processed bones (and thus meats) is examined....

- Evaluation of alpha radiation-induced respiratory carcinogenesis in Syrian hamsters: total dose and dose-rate.

- Further assessment of the effects of occupational radiation exposure in the United Kingdom Atomic Energy Authority mortality study. The United Kingdom Atomic Energy Authority mortality study was designed to investigate the relation between exposure to ionising radiation and mortality...

- Human investigation and informed consent.

- Imaging capabilities and dose considerations of different mammographic units.

- Intraluminal radiotherapy in esophageal cancer. An update. Oesophageal cancer is severe illness leading usually to death. Radical surgery is the most successful treatment but most patients are not operable at the...

- Iodine-125 therapy for thyrotoxicosis: background and evaluation in 148 patients.

- Ion parametric resonance: resolving the signal-to-noise-ratio paradox. Lednev's (1991) "possible mechanisms for the influence of weak magnetic fields on biological system" involved two parallel magnetic fields, one constant and...

- Job related mortality risks of Hanford workers and their relation to cancer effects of measured doses of external radiation.

- Laser-induced collagen remodeling and deposition within the basilar membrane of the mouse cochlea. The cochlea is the mammalian organ of hearing. Its predominant vibratory element, the basilar membrane, is tonotopically tuned, based on the spatial...

- Magnetic field effects in Arabidopsis thaliana cryptochrome-1. The ability of some animals, most notably migratory birds, to sense magnetic fields is still poorly understood. It has been suggested that this "magnetic...
