Radioactive substances
Conventional sources of energy are those that have been used for a long period and are found in limited supply in nature, such as fossil fuels and nuclear materials. Radioactive substances, primarily Uranium and Thorium, are classified as conventional sources because they are non-renewable and have been utilized for large-scale power generation for decades.

E=╬Фmc2 тАФ Energy released from nuclear fission
Q=mc╬ФT тАФ Heat energy transfer in the coolant circuit
Nuclear power generation works on the principle of nuclear fission, where heavy nuclei of radioactive elements like 235U are bombarded with neutrons. This process releases a massive amount of heat energy, which is used to generate steam in a reactor to drive turbines connected to electric generators. The energy released per reaction is given by E=╬Фmc2.
Conventional sources are finite and depletable (Non-renewable).
Radioactive substances provide high energy density compared to fossil fuels.
Nuclear power plants contribute significantly to the base load of a grid.
Solar, wind, and geothermal are categorized as non-conventional or renewable sources.
High energy density, requiring small amounts of fuel.
Does not emit greenhouse gases like CO2тАЛ during operation.
High capital cost for reactor construction.
Complex management of radioactive waste and safety protocols.
Base load power generation in electrical grids.
Nuclear-powered marine vessels.
Research and isotope production.
Radioactive decay is a stochastic process characterized by a half-life T1/2тАЛ.
Options A (Solar), C (Geothermal), and D (Wind) are renewable or non-conventional sources as they are naturally replenished and inexhaustible.
B is correct тАФ Radioactive substances are finite, non-renewable energy sources that have been traditionally utilized for electricity generation.
Always remember that 'Conventional' refers to the historical maturity of the technology and non-renewability, while 'Non-Conventional' often refers to renewable/emerging technologies.
