Investigation of radioactive radon daughters removal methods from copper surface

He jishu, 2021
BackgroundCopper is one of materials often used in rare decay experiments due to its low intrinsic radioactivity. During the installation and assembly of detectors, copper parts may be exposed to air-born radon, therefore the decay daughters of radon ...

Angular bremsstrahlung during $\alpha$-decay, emission from the internal region and unified formula of the bremsstrahlung probability

, 2009
Model of angular bremsstrahlung of photons emitted during $\alpha$-decay is presented. A special emphasis is given on development of unified formalism of matrix elements in the dipole and multipolar approaches.

Potential Radiological Dose of 210Po to Several Marine Organisms in Coastal Area of Coal-Fired Power Plant Tanjung Awar – Awar, Tuban

Ilmu Kelautan, 2022
NORM (Naturally Occurring Radioactive Material) is a radionuclide element that naturally already exists in the earth. Its concentration can be increased by industrial activities, such as coal-fired power plant (CFPP).

Angular analysis of bremsstrahlung in alpha decay

, 2006
A new quantum electrodynamical method of calculations of bremsstrahlung spectra in the $\alpha$-decay of heavy nuclei taking into account the angle between the directions of $\alpha$-particle motion (or its tunneling) and photon emission is presented ...

Surface roughness interpretation of 730 kg days CRESST-II results

, 2012
The analysis presented in the recent publication of the CRESST-II results finds a statistically significant excess of registered events over known background contributions in the acceptance region and attributes the excess to a possible Dark Matter ...

Abrupt changes in alpha decay systematics as a manifestation of collective nuclear modes

, 2010
An abrupt change in $\alpha$ decay systematics around the N=126 neutron shell closure is discussed. It is explained as a sudden hindrance of the clustering of the nucleons that eventually form the $\alpha$ particle. This is because the clustering induced

Atmospheric radioactive nuclide deposition on the coast of the Maowei Sea, northern Beibu Gulf, China

Frontiers in Marine Science, 2023
The natural radioisotopes 7Be, 210Pb, and 210Po, with different half-lives, are all particle-reactive and serve as natural tracers to study sources and transportation of sediments, sedimentation rates, and sediment chronology.

A Review and Outlook for the Removal of Radon-Generated Po-210 Surface Contamination

, 2017
The next generation low-background detectors operating deep underground aim for unprecedented low levels of radioactive backgrounds. The deposition and presence of radon progeny on detector surfaces is an added source of energetic background events.
