3.  Idea was introduced in 1950and patented to
Tracer Lab.
 Radioisotope electric power system developed by
Paul Brown.
 Chemical batteries require frequent replacements
and are bulky.
 Fueland Solar cells are expensive and requires
sunlight respectively.
INTRODUCTION

4.  Usesemissions from radioactive isotope to
generate electricity.
 Nuclear batteries have lifespan uptodecades.
 Do not dependon nuclear reaction , so no
radioactive wastes.
 Canbe used in inaccessible and extreme
conditions.

5. METHODOLOGY

6.  Stage1:No movement of charges due to
equilibrium state of PN-junction.
 Stage2: Introduction ofradioactive source.
 Stage3:Colloision of betaparticals.
 Stage4: Creation ofFermi potential.
 Stage5:Movement of electrons from electrodeA
to RLload.
 Stage6: Returning of electrons to ground state.

8.  Life span-minimum of 10years.
 Reliable electricity.
 Lighter withhigh energy density.
 It isefficient.
 Fuelused is the nuclear waste from nuclear
fission.
MERITS

9.  High initial cost ofproduction.
 Energy conversion methodologies are not
much advanced.
 Regional and country-specific laws regarding
use and disposal ofradioactive fuels.
 To gain socialacceptance.
DEMERITS

10.  Spaceapplication
 Medical application
 In Mobiledevices.
 Itcan be used in
Automobiles
APPLICATIONS

11.  Smallcompact devices of future, requires
small batteries.
 Nuclear batteries increase functionality, reliability
and longevity.
 Until final disposal all Radiation Protection
Standards must bemet.
 Batteries ofthe near future.
