| Research Abstract |
The emission probability of LX rays for plutonium isotopes is one of the most important parameters for high precision estimation of the amount of the in take of plutonium isotopes by using the in vivo counting. Amicrocalorimeter with the sensor (TES) was developed and the excellent energy resolution of 50eV FWHM value was obtained in spectroscopic measurements of LX-rays emitted by transuranium elements with
