ANS webinar to focus on low-dose radiation risk
Join ANS on Thursday, January 21, at noon (ET) for a Q&A with an expert panel as they discuss how to communicate about the risk of low-dose radiation. “Talking About Low-dose Radiation Risk” is a free members-only event that serves as a follow-up to the “Risky Business” President’s Session that took place during the ANS Virtual Winter Meeting last November. The session will take a deeper dive into the many questions generated from the thought-provoking discussion.
Register now to attend the webinar.

The CHIANTI spectral code consists of two parts: an atomic database and a suite of computer programs, written in both the Python and IDL languages. Together, they allow the calculation of the optically thin spectrum of astrophysical objects and application of spectroscopic plasma diagnostics to astrophysical spectra. The database includes atomic energy levels; wavelengths; radiative transition probabilities; collision excitation rate coefficients; ionization and recombination rate coefficients; and data to calculate free-free, free-bound, and two-photon continuum emission. All data and programs are freely available at http://www.chiantidatabase.org and in SolarSoft, while the Python interface to CHIANTI can be found at http://chiantipy.sourceforge.net.
