More than 150 allegations of sexual abuse have been made against 81 BBC employees since the Jimmy Savile scandal engulfed the corporation last year.
Half of the accused are members of BBC staff or contributors, a Freedom of Information request revealed.
Of the cases involving those 40 employees, 10 remain outstanding and are being investigated by either the police or the BBC.
The figures reveal a seismic shift in the number of people coming forward in the wake of the Savile controversy.
A BBC spokesman said the organisation had been appalled by the allegations of harassment and abuse that had emerged since the scandal broke and insisted that a series of reviews were under way to ensure that lessons could be learned.
Twenty-five recent allegations involving current employees have been reported to the police, the majority of which resulted in no further action being taken. Five remain outstanding. Three resulted in no police action but are under investigation at the BBC.
Fifteen were not deemed to be criminal in nature and were investigated internally, resulting in one person receiving an informal warning and two people losing their jobs. Two remain under investigation.
The BBC has been embroiled in sex abuse scandals since it emerged Savile had never been apprehended for abusing an "unprecedented" number of children and adults.
Veteran presenter Stuart Hall was described as an "opportunistic predator" after admitting indecently assaulting 13 girls as young as 9.
A BBC report found that there had been 37 formal complaints of sexual assault in the six years up until last November. The 152 "allegations of a sexual nature" made since October 3 last year demonstrate how much more confident alleged victims have felt in coming forward since being encouraged to do so by the corporation.
The figures also disclose that in the past five years, 39 complaints have been made about sexual discrimination and 22 about race.
A BBC spokesman said the corporation had been appalled by the claims of harassment and abuse that had emerged since the scandal broke.
The corporation had asked staff and contributors both past and present to share any information that might be useful.
