. Board in the Perkins proceeding, -.! releases in approximately that amount would have an insignificant environmental (i.e.,
health) effect and, as such, need not be factored into the cost / benefit balance for the facilities which is mandated by the National Environmental Policy Act.
In the view of the majority,3_/ before that question could be reached by us, the intervenors in the present proceedings (who were not parties to the Perkins proceeding) had to be given an opportunity to "present and prove their case" that, contrary to the conclusion of the Perkin,g Licensing Board, the fuel cycle-related radon releases would have significant health effects.

The two dissenting members- ! thought, however, that the intervenors had already been given that opportunity and had not availed themselves of it.

The radon release rates determined in ALAB-640 did not differ significantly from those upon which the Perkins Licensing Board based its conclusion regarding environ-mental effect.

Messrs. Rosenthal, Salzman and Moore.
Since the rendition of ALAB-640, Mr. Salzman has resigned from the Appeal Panel

and has been replaced as a member of the Hope Creek Appeal Soard by Mr. Rosenthal.
The four Appeal Panel members participating in this order will consider and decide the health effects issue.which still remains open.

- Further, as the dissenting members saw it, the disclosures
)
in the Perkins record (which has been incorporated in the record of these proceedings) fully supported the result reached by the Licensing Board in that case.
In this connection, they pointed to the fact that (1) the fuel cycle-related radon emissions are
" negligibly small compared to natural emissions";5 / (2) the amount of natural radon found in the environment varies widely from one geographic area to another; (3) indoor concentrations of natural radon exceed outdoor cencentrations by, on the' aver-age, a factor of 30 and themselves fluctuate over a substantial range; and (4) "[t]he incremental addition to the outdoor radon concentration due to a single typical nuclear plant" is less than 1/10,000 of that concentration.'_ Taken together, these con-siderations persuaded them that "any assignment of environmental impact to [that] incremental addition could only be characterized as remote and speculative" and, as such, "may properly be ignored in the assessment of the overall environmental impact of a nuclear power plant".

No party sought Commission review of ALAB-640 and the Commission has now determined not to review that decision l

j 5/
" Natural emissions" refers to radon releases to the environment which have as their source such things as j
ordinary building materials and soil.
These emissions produce " natural background radon".
. -. -... ~
. l on its own initiative.
Consequently, finality has attached to our determinations regarding the amount of the radon emissions attributable to the mining and milling of uranium fuel for the facilities at bar.
This being so, the time has arrived to provide the intervenors with their opportunity to demonstrate, if they can, that radon emissions in that amount will produce a substantial enough incremental environ-mental effect both (1) to require consideration in the NEPA cost / benefit balance for each facility; and (2) to tip that balance against plant operation.
As the ALAB-640 majority took pains to note, 13 NRC at fn.96, a hearing on these questions is not inevitable.
Whether one will be necessar-f wholly depends upon the ability of the intervenors to demonstrate the existence of a genuine issue of material fact respecting any of the issues they pre-viously raised concerning the environmental significance of fuel cycle-related radon emissions.
See id. at fn. 92.
In the totality of circumstanco., there is nothing un-reasonable about requiring the intervenors thus to shoulder (as plainly contemplated by the ALAB-640 majority) the burden of going forward on the question of the need for a further hearing on environmental impact.
Once again, the subject of I
health effects was thoroughly explored in the Perkins evi-I dentiary hearing in the context of fuel cycle-related radon
. emissions not dissimilar in amount to those later determined by us in these proceedings.
And the Licensing Board's con-clusion in that case that the incremental radon contribution of the uranium fuel cycle would not have significant health effects was grounded upon the testimony of highly qualified expert witnesses.
See LBP-78-25, supra, 8 NRC at 95-100.
One such witness was Dr. Leonard B. Hamilton, a physician who headed the Biomedical and Environmental Assessment Division at the Brookhaven National Laboratory.
For over thirty years, Dr. Hamilton had been involved in the appraisal of radiation health risks.
Prior to joining Brookhaven in 1964, he had spent 14 years on the staff of the Sloan-Kettering Institute for Cancer Research in New York City and had also served on the faculty of the Cornell University Medical College.5 !
Re-ferring to the testimony of other expert witnesses for the appli-cant and the staff, Dr. Hamilton had this to say:
"As can be l
seen [from that] testimony, the additional Radon-222 from the l
mining and milling [ phases] of the uranium fuel cycle makes an additional negligible contribution to annual natural background radiation and consequently,~a similarly negligible impact on the health effects associated with the fuel cycle" (emphasis sup-7 plied).- /

For a fuller statement of the impressive qualifications possessed by Dr. Hamilton, see Duke Power Co. (Perkins Nuclear Station, Units 1, 2, and 3), Docket Nos. 50-488, 50-489, 50-490, fol. Tr. 2256.

Hamilton testimony, fol. Perkins Tr. 2266, at p.
2.
This statement was quoted by the Perkins Licensing Board, 8 NRC at 98.
. Not having been parties to Perkins, the intervenors now before us cannot be deemed bound by Dr. Hamilton's conclusions.
(This is so even though Dr. Chauncey Kepford, the representative of the Peach-Bottom - Three Mile Island intervenors, was per-mitted to cress-examine him on behalf of the Perkins inter-venor$ /).
But in the absence of a concrete threshold showing that there is a difference in competent expert opinion on the health effects issue, there is wholly insufficient cause to re-quire either the applicants in the instant proceedings or the staff to replow at yet another hearing the ground previously traversed by Dr. Hamilton and the other Perkins witnesses.
As a condition precedent to the holding of a further evi-dentiary hearing addressed to the environmental effects of the radon releases associated with the uranium fuel cycle, the inter-venors therefore must make that showing.
Although we obviously have to leave the precise ingredients of the showing to them, a word of caution is in order.
The burden of demonstrating the l
1 existence of a genuine issue of material fact will not be satis-fled by anything short of the documented opinion of one or more qualified., authorities to the effect that-the incremental fuel cycle-related radon emissions will have a significant environ-mental effect in terms of human health.
Further, we will expect i

. that any such opinion will explicitly take into account (1) the comparative relationship between the amount of those emissions (as found in ALAB-64 0) and of natural radon emissions; and (2) the fluctuations in natural emissions (indoor vis a vis outdoor as well as from one geographic area to another).
More particularly, an explanation should be forthcoming respecting the basis upon which it.
concluded by the expert (in disagree-ment with Dr. Hamilton and other Perkins witnesses) that a very small increment to natural background radon, falling well 'within the fluctuations in natural ra6on levels, might have significant health effects of its own.
The intervenors' preliminary showing is to be filed and served within 60 days of the date of this order.
Upon its receipt, we will fix the time for responses from the other parties.
It is so ORDERED.
