The Raja Ramanna Centre for Advanced Technology (RRCAT), an Indore-based unit of Department of Atomic Energy (DAE) has developed an instrument called Fluorimeter, to measure traces of uranium in water. The device is capable of examining traces of uranium in sample of water from 0.1 PPB (Parts-per- billion) unit to 100 PPB.  It can be easily taken anywhere and water can be taken from any source for testing to instantly reveal if uranium traces present in water.
