Methods of Safe Handling of Radionuclides and Pertaining Rules and Regulations
Two-dimensional imaging, even with multiple views, does not provide accurate three-dimensional information concerning radionuclide distribution. Because two-dimensional imaging more or less integrates the information from the third dimension (depth),…
Biological Effects of Radiation and Risk Evaluation from Radiation Exposure
Two-dimensional imaging, even with multiple views, does not provide accurate three-dimensional information concerning radionuclide distribution. Because two-dimensional imaging more or less integrates the information from the third dimension (depth),…

Therapy of Inflammatory Joint Diseases (Radiation Synovectomy, Radiosynoviorthesis)
Fig. 1 At the center is the rheumatologist. Often it is artistic work to juggle with antirheumatoid drugs. Sometimes a drug fails or the whole show ends up as a complete…
Medicine Dose Assessment
(1) where = absorbed dose rate to a target region of interest (Gy/sec or rad/hr) A S = activity (MBq or μCi) in source region S y i = number of radiations…

Dosimetry, Radiobiology, and the Previously-Treated Patient
(1) Since lethal lesions are Poisson-distributed across a cell population, the probability that a large population of cells will undergo a certain number of lethal lesions (i.e., the surviving fraction,…
