The Nuclear Science Laboratory, Department of Physics, Fourah Bay College has been defunct for the past 30 years, owing to the lack of needed equipment to kick-start the lab which deals mainly with radiation and its attendant problems.

Quite apart from the unavailability of equipment to furnish and refurbish the Nuclear Science Department since that time, the inconsistency of power supply in the country has been one of the primary causes for the premature closure of that vital department.
