Abstract: We are developing metallic magnetic calorimeters for beta spectrometry in the context of ionizing radiation metrology. The aim is the determination of the shape factors of beta spectra. Our latest detector has been designed to measure the spectrum of <superscript>241</superscript>Pu, a pure beta emitter with an endpoint energy of 20.8 keV. We present the spectrum resulting from our first measurement and compare it with theoretical spectra. [ABSTRACT FROM AUTHOR]
