Re: RE: DOT SURVEYS

You state that: 
 
It was my   = 
understanding that these surveys are required for those who offer Class 7   = 
= 
material for shipment, not those who receive it.  DOT only has   = 
jurisdiction on material in transit.  Normally your site specific   = 
procedures govern receipt surveys. 
 
This is not entirely true.  If the package is licensed material, its receipt 
is regulated by 10CFR20.1906, "Procedures for receiving and opening packages." 
 With some exceptions, this requires surveys.  It especially requires the 
receiver to: 
 
"Monitor all packages known to contain radioactive material for radioactive 
contamination and radiation levels if there is evidence of degradation of 
package integrity..." 
 
If the radiation or contamination levels exceed those of 10CFR71, which are 
substantially the same as the DOT limits, the incident must be reported 
"immediately". 
 
The opinions expressed are strictly mine. 
Here's to a risk free world, and other fantasies.

Jim:

The limits in 49 CFR 443, Table 10 are per square cm.  The reg states   =
that levels of non-fixed contamination may be determined by wiping an   =
area of 300 cm2.  Personnel who are trained to take 100 cm2 wipes, may do   =
=
so on package surfaces.  You must have a sufficient number of wipes in   =
appropriate locations for your application.  In order to use Table 10,   =
you would have to calculate the activity per cm2.  It was my   =
understanding that these surveys are required for those who offer Class 7   =
=
material for shipment, not those who receive it.  DOT only has   =
jurisdiction on material in transit.  Normally your site specific   =
procedures govern receipt surveys.

     Radsafers,
       =

     As I understand the DOT and NRC regulations, the contamination   =
limits
     for receipt surveys of packages are listed "per 300 cm sq".  What is  =
 =

     the accepted interpretation of this limit:
       =

                a.  Does it mean that the surveyor must survey at least   =
50
     cm sq over the 6 sides of a boxed package?
       =

                b.  Does it mean that the surveyor can survey 100 cm sq   =
and
     relate the results to 300 cm sq equivalent?
       =

                c.  Does it mean that the surveyor can survey 300 cm sq   =
on
     the side of the package most likely to indicate contamination?
       =

                d.  None of the above
       =

     Thanks in advance for your assistance.
