Abstract

Light weight radioisotope (LWR) ⁸⁹Sr and ⁹⁰Sr could be obtained from used rods in fission atomic plants. The economics of the disposal of nuclear bars indicate the convenience to develop added value applications. The difference in t_1/2 allows ⁸⁹Sr to deliver its energy at a rate 200 times higher than ⁹⁰Sr. A large emission number of low penetrating power particles in a short time characterize ⁸⁹Sr, which allows that these highly radioactive LWR involves a rather limited danger. Chemical similitude of calcium and strontium uptake has led to the use of ⁸⁹Sr in treatment of bone cancer metastasis. ⁸⁹Sr damages animal tissues because ionize water, but penetrates through the skin about: 5 to 8 mm. Hence, to obtain it in insoluble form, like obtaining ⁸⁹Sr silicate, could make possible its wider use. Purifying ⁸⁹Sr from contaminant ⁹⁰Sr allows that after one year do not leave any contamination. LWR could be covered with scintillators substances, which by subtracting kinetic energy from beta-radiation, emit light and function as a major source of shielding. This treatment engineers Radioisotope Light Generators (RLG). Their light could activate photovoltaic cells (PV), which could lead to nano-devices without moving parts RLG-PV.
