The neglected activation of tantalum in reduced activation materials

open access: yesNuclear 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

Comparison of regional blood flow values measured by radioactive and fluorescent microspheres [PDF]

open access: yes, 2002
Fluorescent microspheres (FM) have become an attractive alternative to radioactive microspheres (RM) for the measurement of regional blood flow (RBF). The aim of the present study was to investigate the comparability of both methods by measuring RBF with

Fukushima and Chernobyl: Similarities and Differences of Radiocesium Behavior in the Soil–Water Environment

open access: yesToxics, 2022
In the wake of Chernobyl and Fukushima accidents, radiocesium has become a radionuclide of most environmental concern. The ease with which this radionuclide moves through the environment and is taken up by plants and animals is governed by its chemical ...

Influences of cosmic radiation, artificial radioactivity and aerosol concentration upon the fair-weather atmospheric electric field in Lisbon (1955–1991) [PDF]

open access: yes, 2006
The atmospheric electric field is influenced by cosmic radiation, radioactivity and aerosols. In this work we investigate the existence of: (i) correlations between relative anomalies of annual values of atmospheric electric field and cosmic radiation ...

Equilibrium status of naturally occurring 226Ra with radon daughters and estimation of 238U activity from 235U using natural radioactivity ratio of 238U/235U in soil around Rawatbhata, Rajasthan

open access: yesRadiation Protection and Environment, 2022
Equilibrium status among 226Ra and radon daughters was studied in soil samples around Rawatbhata, Rajasthan. It was found that the increase in radioactivity of 214Bi (radon daughter) due to complete radon buildup in the sealed container is within 15 ...
