Dear Dr. Wogman:
I have reviewed your monthly report for the " Environmental Cleanup Standards" (B-2216) for December,1981, and have the following comments:
1)
Your revised Table I showing the results of grab versus RPISU radon progeny measurements is acceptable.
This data supports the present Edgemont grab sampling protocol guidelines.
The discussion should be finalized to indicate that where RPISU measurements have been made versus the 5-minute grab Working Level sample:
a)
There is 100% correlation that for grab WL samples less than 0.01 WL, the annual average RPISU was less than 0.015 WL (based on 8 structures monitored).
b)
For the 82 structures having grab WL samples between 0.01 and 0.033 WL, the annual average RPISU was greater than 0.015 WL for 28% of those structures.
c)
There is 100% correlation that for grab WL samples greater than 0.033 WL, the annual average RPISU was greater than 0.015 WL (based on 3 structures monitored).
2)
Your discussion and Table II regarding the results of limited Track Etch @ sampling is confusing.
So that the reader may make a direct comparison of the RPISU versus the Track Etch @ and the 5-minute grab WL sampling, it is suggested that a table similar to Table I be provided to show the correlation between the Track Etch @ results and the grate WL samples.
3)
Your discussion and Table III regarding RPISU versus Track Etch @
results indicates that 10 out of 30 structures would fail the DIST:

TE3 9 1982 0.015 WL criteria based on the Track Etch 3 data thereby resulting in an erroneous conclusion for 30% of the structures monitored by Track Etchs.
As shown in Table I, such an erroneous conclusion was not obtained using the simple 5-minute grab WL sar..pling technique.
Therefore, based on your Table III data, it would seem that Track Etch 8 is unacceptable as compared to the 5-minute grab WL sample.
This conclusion is contrary to your discussion on page 4 of your December, 1981 report and, therefore, needs to be resolvec.
4)
Your discussion and Table IV regarding the 5-minute grab WL sample correlation with the soil radium measurements i.s acceptable.
You should complete a comparison between the RPISU and the radium in soil measurements.
5)
As previously requested, you should present a graphical display of the data contained in all of your tables.
6)
Enclosed is a letter from the State of South Dakota concerning their review of your draft report.
I celieve all of these comments are constructive and should be incorporated in your final text.
7)
Also enclosed is a letter froin the U.S. EPA concerning their review of your draft repo'rt.
The EPA's specific comments concerning the uncertainties of the indoor Working Level assessment are certainly pertinent and such a discussion should be included in your final text.
Also, EPA':s dicussion of the significance of the total quantity or Curie activity of radium at a property and the cost / benefit to remove such material should be discussed in your final t' ext.
I, therefore, suggest that you contact Mr. Joseph Hans of the EPA (FTS-545-2461) and ask permission to cite his work in your report.
8)
Comments by the DOE on your draft report have not been received yet but I will send them to you as soon as they are available.
- However, you should proceed at this time to finalize your report cons.idering the comments of the State and EPA as discussed above.
Your final draft report is due by March 31, 1982.
