General Information

Filling the Phantom

1

1-3





If a small bubble of air remains, raise the filling
corner of the phantom by tilting the camera detector
about 1/8” to ¼”, so the bubble will remain in the
side arm of the liquid-filled region.


The flood phantom is now ready to use.

1.4 Draining the Phantom

To empty the phantom, remove both the filler and vent plugs and the “O” rings, and invert over an
appropriate drain. Remove the drain vent plug now located on the top edge of the phantom.


Make sure that the radioactive solution being
drained is below the maximum permissible
concentration, which the N.R.C. (or your agreement
state) will allow to be discharged into public
drainage systems. If it is not, (a) hold the solution
in a separate container until it decays below this
value or (b) dilute the solution below the
maximum permissible level.

1.5 Maintenance

Cleaning

Use any mild detergent in warm water.

Care of Filler and Vent Plugs

Lubricate the threads of both plugs regularly with good silicone grease or a stopcock lubricant.


Do not use organic solvents, (they will attack the
phantom walls). As an algaecide, use 2 cc of
copper sulfate solution, made by dissolving 5
grams of copper sulfate in 100 cc of water.

Alternatively, use 5 to 10 drops of Lugol’s Solution
(iodine) or any common swimming
pool algaecide (chlorine).
