情態副詞

So we're putting paper towels down to soak it up

We're also going to get some plastic bags and

You don't want to track material around but you

Definitely don't want to get it on the bottom of your own shoes

So this way if we get contamination on the

Bottom of the shoes it won't be on the shoes

Then we put all that soaked up liquid and the

Radioactive waste container or in a plastic bag

Take up the absorbant paper that got contaminated

Continually check your hands to make sure they're not contaminated

Finding out where the area of contamination is

And marking it off so we know how to work

We're going to clean from the outside towards the inside

Paper towels and a soapy solution like Alconox

Wet the area down with it take a paper towel and

Only a small area and we'll check that to see if

And keep cleaning until no more contamination

We don't spread contamination inadvertently

And then we'll check for removable contamination

It to somebody with a liquid scintillation counter

Checking the areas and again frequently checking the gloves

You clean a little bit, you verify that stuff is coming up

Then once it's clean and no more material is coming up

Doing the same process, cleaning small area

It may be that some areas may need a little bit of

An abrasive cleaner like Commet or something

Or if there may be a hot spot still there

By counting it in a liquid scintillation counter

Occasionally you'll have a situation where

There'll be fixed contamination in a crack

And it won't come up and we can deal with that

When you're finally done your shoe covers

And then you need to survey yourself afterwards
