Re: Package Monitoring
49 CFR has requirements for package radiation, thermal &
contamination (173.441, .442, .443).
Contamination and radiation levels should be checked upon arrival of the
package. The radiation levels on the bottom of packages is the most
missed reading on radioactive shipments. I have seen a lead pig designed
for a source read 100 mr/hr on the bottom of the container. The pig
weighted 100 lbs. as long as the pig sat on thr floor the readings were
under 40 mr/hr on the top and sides. The high readings was discovered
when we attached the pig to an over head crane to read the bottom of the
container. The manufacturer sent a larger shipping pig to replace the
improper one. The FAA was informed of the situation and an investigation
was conducted.
