Radioactivity in Lutetium metal
On July 5, 2017 In Special material
Lutetium is silvery grey metal element belonging to the group of rare earth metals (lanthanides) as its last member which closes it. Unlike some other lanthanides, lutetium is relatively stable at dry air, but is readily oxidized in humid environment and at higher temperatures. Lutetium has highest hardness (Brinnel - 893 MPa), density (9.84
Cobalt-60 gamma spectrum
On June 11, 2017 In Special material
In this post I would like to present gamma spectrum of cobalt-60 radioisotope. This isotope has many industrial and medical uses, for instance in gamma defectoscopy, thickness measurement, tools and food sterilization or in radiotherapy. One gram of cobalt-60 has huge activity - about 44 terabecquerels (TBq). By the way, if one would hang around
