's Q.4.
Why-is this issue relevant to_ LEA-12?
A.4.
Contention LEA-12 asserts in part thatLthere has been
~
no. determination of which school district buildings are
-adequate for sheltering, which will bear on teachers / school staff willingness to remain on duty during a radiological emergency.
Q.5.
What is your' response to this concern?
A.S.
Adequate sheltering means a
winter worthy house or commercial structure with a basement in the northeastern United States.
~According to NUREG/ll31,
" Examination of Offsite Radiological Emergency Protective Measures for Nuclear Reactor Accidents Involving Core Melt,"
this kind of structure
- should, on the
- average, provide a
dose reduction factor (DRF) of 0.5 against airborne k
radioactivity and 0.08 against general shine.
These values may be compared with_a DRF against airborne radioactivity of 0.75 and against ground shine of 0.33 for houses in_the southwest.
In addition, sheltered individuals will inhale roughly 35% less than those outside during cloud passage.
With tight construction apd reduced ventilation
- rates, larger reductions are possible.
Q.6.
What does the ' Commonwealth's plan state regarding building adequacy fo?. sheltering?
