Olympic organiser Locog is working with airport security equipment specialist Rapiscan Systems to supply the kit needed to safeguard the Olympic Park and 34 other competition venues across the UK.
A typical entrance point will comprise of two walkthrough metal detectors and two x-ray machines.
There will also be a list of prohibited and restricted items similar to the one found in airport security banning liquids, sharp objects and flammables.
The current threat assessment for London is moderate, but is likely to go up to severe during the Games.
Ian Thomas, head of venue security for Locog, told Event the Olympic Park is considered to be high risk and will be operated on an "island site" principle.
The challenge, he said, is getting the balance between the right level of security and people still enjoying themselves.
"We could run a security regime that makes it really difficult for spectators to get in, but we can’t have a whacking great queue outside, or what you end up with is a crowded place that could be a target for terrorists," he explained.
The Olympic Stadium itself will go on "lock down" from early June once police have carried out a search to make sure nothing inside could cause a threat. A fence will then be erected around it with everything going in and out subject to search.
"If you imagine if you picked up that stadium turned it upside down and shook it out everything that’s in there has got to be searched before it goes in," said Thomas.
Due to space constraints football stadiums will be subject to different security measures with individual person bag searches.
