Maximum.Permicaible Concentration (MPC)

In addition, the fol-lowing values are used:

Measurement Methoda I

Liquid e f fluent measurementa for r, conc radioactivity are per-formed by camma analynin on a Ge-Li detector for each tank diocharged.

A composite nample is created by collecting representative amounts from each tank batch diccharged and it in analyzed monthly for Tritium, strontium 89 and 90, and Gross alpha activity.

In addition,

  • each tank 13 analyzed for alpha concentration and the h'igher of j

these two analysen in the bania for the valuca reported in Table I, B

Item l.

Airborne gaseous effluento are determined by gamma analynia i

1 on a Go-Li detector of nampics from the various flow paths.

The analysis includen a deter-ination of ganeous halogen content.

h' Airborne particulate and particulate halogen releacen are determined by gamma analysin on a Go-Li detector of weekly camples of stack dicchargen on glaca riber filter paper and charcoal cart-ridr boorbants.
