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

On July 2, 2017 In Background radiation
Beryllium is a steel grey hard and brittle metal with relatively low density, high thermal capacity and high sound conductivity. Due to its interesting physical-chemical characteristics, it has many uses in special materials used for example in aerospace applications or electronics. Main drawback of beryllium and its compounds is really high
