Mutagenicity of radon and radon daughters [PDF]
, 1991 The objective of our research is to investigate the dose-response relationship of the lethal and mutagenic effects of exposure of cells to radon and its decay products. Dose rate dependence and the nature of the DNA lesion will be studied, using the thymidine kinase and HPRT loci to measure mutation frequency.

Contribution of Radon and Radon Daughters to Respiratory Cancer [PDF]
Environmental Health Perspectives, 1986 This article reviews studies on the contribution of radon and radon daughters to respiratory cancer and proposes recommendations for further research, particularly a national radon survey. The steady-state outdoor radon concentration averages 200 pCi/m3, and indoor levels are about 4 times higher.

Reconstruction from Radon projections and orthogonal expansion on a ball [PDF]
, 2007 The relation between Radon transform and orthogonal expansions of a function on the unit ball in $\RR^d$ is exploited. A compact formula for the partial sums of the expansion is given in terms of the Radon transform, which leads to algorithms for image reconstruction from Radon data.

Inversions for the Hua-Radon and the polarized Hua-Radon transform [PDF]
arXiv, 2021 The Hua-Radon and polarized Hua-Radon transform are two orthogonal projections defined on holomorphic functions in the Lie sphere. Both transformations can be written as integral transforms with respect to a suitable reproducing kernel. Integrating both kernels over a Stiefel manifold yields a linear combination of zonal spherical monogenics.

Procedia Earth and Planetary Science, 2014 AbstractRadon, a natural radioactive element present in air, soil and water, has been proved to be related to lung cancer: according to the US EPA, nearly 10% of lung cancer deaths are attributable to radon, while Spanish studies estimate this figure is about 5%.Hence, a wide number of research works have been carried out worldwide to determine the ...

Quantum Radon Transform and Its Application [PDF]
arXiv, 2021 This paper extends the Radon transform, a classical image processing tool for fast tomography and denoising, to the quantum computing platform. A new kind of periodic discrete Radon transform (PDRT), called quantum Radon transform (QRT), is proposed. The QRT has a quantum implementation that is exponentially faster than the classical Radon transform ...

A continuous image of a Radon-Nikodým compact which is not Radon-Nikodým [PDF]
Duke Math. J. 162, no. 12 (2013), 2285-2299, 2011 We construct a continuous image of a Radon-Nikod\'ym compact space which is not Radon-Nikod\'ym compact, solving the problem posed in the 80ties by Isaac Namioka.

Development of new radon monitoring systems in the Kamioka mine [PDF]
Progress of Theoretical and Experimental Physics, Volume 2018,
Issue 9, 1 September 2018, 093H01, 2018 Radioactivity from radon is a major threat for high-precision low energy physics experiments like the ones in the Kamioka Mine. We developed a new high sensitive radon monitoring system and conducted systematic radon concentration measurements for the first time in Kamioka.
