Discovery of Radioactivity [PDF]
Nature, 1948 I AM surprised that Prof. Becquerel should have read into a passing reference to his distinguished father‘s work, in my review of Prof. Gamow‘s book, any suggestion that the discovery of radioactivity was in any way "fortuitous". No such suggestion was intended.

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

Time changes of dose equivalent rate above the soil surface as indication of natural attenuation processes [PDF]
Proceedings of the International Association of Hydrological Sciences, 2019 Eight sites in the Fukushima contaminated area were surveyed for long-term changes in D-shuttle dose equivalent rate above the soil surface during 2015–2017. D-shuttle readings in most cases decreased faster than if due to radioactive decay only.

The neglected activation of tantalum in reduced activation materials
Nuclear Materials and Energy, 2023 Due to the expression of “reduced activation”, the severe radioactivity of tantalum (Ta) after neutron irradiation in early decay years is easily neglected. In the presented study, after an irradiation of only 0.3 dpa by fission neutron and followed by a

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