  Extraction of the light weight radioisotopes (LWR) 89Sr/90Sr, from the
expended nuclear bars in the Fukushima reactor, should have decreased the
extent of contamination during the course of the accident. 89Sr applications
could pay for the extraction of 89Sr/90Sr from nuclear residues. Added value
could be obtained by using 89Sr for cancer treatments. Known technologies could
be used to relate into innovative ways LWR, to obtain nuclear energy at battery
scale. LWR interact by contact with scintillators converting \beta-radiation
into light-energy. This would lead to manufacturing scintillator lamps which
operate independently of other source of energy. These lamps could be used to
generate photoelectric energy. Engineering of radioisotopes scintillator
photovoltaic cells, would lead to devices without moving parts.
