You didn't say whether the radio still worked ok apart from the noise... Defective components can produce such noise as can a dry soldered joint - a dry joint is a fairly common fault. A white type noise is typical of many types of receiver when the squelch is turned down. The squelch circuit is designed to reject signals that are too weak to receive with sufficient strength to be intelligible and in doing so also blocks the background "static". On many CB and VHF type receivers the squelch level is adjustable but tends to be either preset or automatic on basic walkie-talkie type radios. Perhaps the squelch requires adjustment or perhaps the circuit has stopped working.
