Verification of the Effectiveness of Risk Communication Materials Using Natural Radiation Levels as a Reference Standard: Results from a Survey of First-Year Health Department Students

Safety
Even before the Fukushima Daiichi Nuclear Power Plant accident, people were continuously exposed to various naturally occurring radioactive materials, including radon. However, public awareness and understanding of this exposure remain limited.

On the (Higher Multipoles) Variance Asymmetry in the Cosmic Microwave Background

The Astrophysical Journal
We have studied the cosmic microwave background (CMB) map looking for features beyond cosmological isotropy. We began by tiling the CMB variance maps (which are produced by different smoothing scales) with stripes of different sizes along the most ...

Forecasting synchrotron spectral parameters with QUIJOTE-MFI2 in combination with Planck and WMAP

Astronomy & Astrophysics
We present a parametric component separation forecast for the QUIJOTE–MFI2 instrument (10–20 GHz) that assesses its impact on constraining polarised synchrotron emission at 1° full width at half maximum and Nside = 64.

A Measurement of Atmospheric Circular Polarization with POLARBEAR

The Astrophysical Journal
At millimeter wavelengths, the atmospheric emission is circularly polarized owing to the Zeeman splitting of molecular oxygen by the Earth's magnetic field.
