Comparison of Panasonic’s Dosimetric System with Gamma-31 Dosimeters

open access: yesJournal of Sustainable Mining, 2013
Equipment being used in medical or industrial institutions is often a source of ionizing radiation with different energies and types, which complicates the detection and assessment of doses. Up until now, for dosimetric measurements of ionizing radiation,

Identifying the Presence of Natural Radionuclides in Ashlar Samples

open access: yesCivil and Environmental Engineering, 2021
Humans have always been exposed to different types of natural and cosmic radiation. At present we experience 83 % natural radiation, for example from granite marbles, building materials such as concrete, brick, granite, or drywall.

Radioactivity and Space Range of Ultra-Low-Activity for in vivo Off-line PET Verification of Proton and Carbon Ion Beam—A Phantom Study

open access: yesFrontiers in Public Health, 2021
Purpose: The radioactivity induced by proton and heavy ion beam belongs to the ultra-low-activity (ULA). Therefore, the radioactivity and space range of commercial off-line positron emission tomography (PET) acquisition based on ULA should be evaluated ...

Generation of nanoparticles in the concentrated energy (laser beam) and gas flow

open access: yesAviation, 2004
The method of generation and selection of small nanoparticles in the airflow is considered in this paper. To melt the material (stainless steel), a concentrated energy flow – a pulsed solid‐state laser beam – was used.

Radioactive Eggs. II. Distribution of Radioactivity in the Yolks [PDF]

open access: yesExperimental Biology and Medicine, 1951
Summary(1) The distribution of radioactivity in the yolks of eggs laid by a hen fed sodium acetate-1-C14 has been determined. (2) The radioactivity appears in all fractions of all yolks in the following order of increasing specific activity: protein, glycerol, phospholipids, fatty acids, cholesterol.
