A quarter of the adult population faces an "anti-paedophile" test in an escalation of child protection policies, according to a report.
The launch of a new Government agency will see 11.3million people vetted for any criminal past before they are approved to have contact with children aged under 16.
But the increase in child protection measures is so great it is "poisoning" relationships between the generations, according to respected sociologist Professor Frank Furedi.
From next year the new Independent Safeguarding Authority will require any adult who come into contact with children or vulnerable adults either through their work or in voluntary groups to be vetted.
But Prof Furedi's report, Licensed to Hug, highlighted examples of when adult-child relationships were distorted by the need for CRB checks already being required by schools and other organisations.
In one example, a woman could not kiss her daughter goodbye on a school trip because she had not been vetted.
In another, a mother was surprised to be told by another parent that she and her husband were "CRB checked" when their children played together.
The CRB said yesterday that it will process 3.6million checks this year - up from 3.4million last year - of which 20 per cent were for volunteers.
Vince Gaskell, the bureau's chief executive, said he did not believe that CRB checks were poisoning the relationship between adults and children. Telegraph
The CRB’s aim is to help organisations in the public, private and voluntary sectors by identifying candidates who may be unsuitable to work with children or other vulnerable members of society. CBR website
