a ABSTRACT A telephone survey of households within 5 miles of TMI and a group from 41-55 miles from TMI was conducted in October, 1980. Three questions were addressed.
- 1) Had distress levels in the 5 mile radius changed in comparison to earlier studies? 2) How did respondents feel about the situation at Three Mile Island and how it was being handled?
- 3) How did respondents react to the venting of Kryptom gas at TMI in July of 1980.
Distress Five distress measures were repeated from earlier surveys, thus allowing comparisons over an 18 month period from April,1979 to October
'1980.
The five measures were:
being upset about TMI, feeling TMI was a threat to safety, reporting of stress related symptoms (2 clusters of symptoms: somatic and behavioral) and, for those respondents who had symptoms, whether they attributed the symptoms to Three Mile Island.
Results showed reductions in distress for both the close and far groups over the 18 month period studied.
There was a sharper rate of reduction for the group close to TMI than for the group 41-55 miles away.
The 0-5 mile group had significantly higher distress than the 41-55 mile group on all measures through January, 1980 but, in October, 1980, differences were no longer statistically significant for stress-related symptoms and for ratings of upset regarding TMI.

, (Abstract Continued)
Attitudes Opposition toward re-starting unit number one at TMI dropped from 60% in January,1980 to 47% in October, 1980 for the group within 5 miles of IMI.
The Nuclear Regulatory Commission and energy experts working for the Pennsylvania Department of Environmental Resources were given the most support for having a say in how the TMI clean-up is carried out.
Respondents in both groups were fairly evenly distributed as to whether to have more or fewer nuclear plants in the future. When asked how much they believed in rumors regarding effects of TMI (e.g.,
rumors of increased miscarriages, increased cancer rates, increase in mental health problems, etc.) respondents were approximately equally distributed between believing and not believing rumors with a tendency for more people to believe than disbelieve the rumors.
For two of the rumors, (an increase in miscarriages and an increase in birth defects) there was greater acceptance 4
of the rumor in the 41-55 mile group than in the 0-5 mile group. Respondents' ratings of media coverage of the TMI situation showed that almost half of the respondents felt the media had blown events and of proportion, approximately 20% thought information had been withheld and less than 1/3 thought that events were reported accurately.
Reactions to Krypton Venting Fifteen percent of respondents within 5 miles of TMI said that they left the area during the venting and that the venting was an important reason for their leaving. The average length of absence due to ventir.g was 10 days. Attitudes toward the venting were significantly more positive among persons close to TMI than among persons in the 41-55 mile group.

INTRODUCTION Several studies of the psychological, social and economic ef fects of the Three Mile Island nuclear accident have been conducted since the crisis in March, 1979. One of these studies, (Houts et al, 1980) carried out by the Pennsylvania State University under auspices of the Pennsylvania Department of Health, showed heightened distress levels near the facility that persisted through January,1980.
Subsequent reports by Bromet (1980) and Bromet and Dunn, (1980) came to similar conclusions, namely, that the population close to Three Mile Island contained many people who were very concerned about the situation there and who also reported heightened levels of symptons frequently associated with stress for as long as a year af ter the original crisis.
The present study, carried out in October, 1980, eighteen months af ter the original crisis, had two purposes:
1) to determine whether distress levels and concerns shown to be elevated close to TMI had changed in the nine months since the Department of Ilealth Survey in January, 1980.
2) to obtain attitudes and opinions on a variety of issues germane
~
to the situation at Three Mile Island which had not been investigated earlier.
These issues included rumors about bad ef fects of the nuclear accident, what groups should influence how TMI is cleaned up, media coverage, the future use of nuclear power plants in this country, and scientists' knowledge of radiation.
METHOD This study was carried out in conjunction with a study of mobility of persons living within 5 miles of Three Mile Island (Goldhaber et al, 1981).
The report of that study contains detailed information about sample selection and interview
2 techniques.
Followir.g is a summary of thosu aspects of the methodology most relevant to this study.
Sample Selection Two groups were studied:
100 respondents living from 41 to 55 miles from Three Mile Island and 400 respondents living within five miles of TMI in October, 1980.
Respondents from 41 to 55 miles away were sel ected in the same manner as in the Nuclear Regulatory Commission Survey in July, 1979 (Flynn, 1979) and in the Pennsylvania Department of Health survey in January, 1980 (Houts et al, 1980).
This made it possible to compare responses from this study to those from the earlier studies.
The sample of persons living within 5 miles of Three Mile Island was constructed from two sub samples of the mobility study:
- 1) persons who were living within five miles of TMI at the time of the Pennsylvania Department of Health census in August, 1979 and who had not moved f rom their dwellings since that time and 2) persons who had moved into dwellings within 5 miles of TMI during the year following the census.
Since there were a larger number of in-migrants in relation to non-migrants in these samples than in the general population, weighting was used to obtain responses characteristic of the general population.*
Telephone interviews were carried out with all groups by Chilton Research Services of Radnor, Pennsylvania. Respondents in the 41-55 mile group were selected using random digit dialing while respondents within 5 miles of Three Mile Island were selected either from Department of Health census lists for the area or, for in-migrants, lists o f persons who moved into vaca ted dwellings or new housing since the TMI crisis.
(See Goldhaber et al, 1981 for detailed description of sample selection.)
- Weightings used in the calculations for the 0-5 mile group were based on a mobility rate of 12.5%.
Af ter these calculations were completed it was determined that the mobility was actually 11.6%.
In order to determine whether new calculations were required, the mean, standard deviation, made and median were computed for demo-graphic variables (age, sex, education, income, and marital status) using the 12.5%
weighting and the 11.6% weighting for in-migrants as compared to non-migrants.
The results, shown in appendix III show almost identical results with the two weightings.
It was therefore decided not to re-compute other analyses.
3 DISTRESS INDICES Both of the earlier surveys (July,1979 and January, 1980) showed heightened distress near Three Mile Island compared to farther away.
The same distress indices used in earlier studies were included in the present study to determine whether this pattern persisted for an additional 9 months (or 18 months af ter the original crisis).
In the July, 1979 and January,1980 surveys distress was measured at all distances out to 55 miles from TMI.
However, the present study only sampled within the 5 mile radius and between 41-55 miles from TMI.
Therefore, to make the results of these studies equivalent, data from the earlier studies were re-analyzed to compare just the group within 5 miles of TFE to the group between 41 and 55 miles away.
Analysis of covariance was utilized controlling for age, sex, education, marital status and income. Results for the five distress indices for the four time periods af ter the TMI crisis are shown in Table 1.
The overall pattern is quite interesting.
Three of the measures which had indicated higher distress close to TMI compared to farther away in April, 19'77, July, 1979 and January, 1980, no longer showed statistically significant dif ferences in October, '1980.
On the other hand, the three other distress measures are significantly different at all four time periods.
1.
Upset ratings were rignificantly higher close to TMI compared to far away from April,1979 through January, 1980, but were no longer statistically different in October, 1980.
An examination of the mean ratings at each time period shows that levels of upset came down over time for both the close and f ar groups, but that the drop was sharper for the groups close to TTH.
2.
Both behavioral and somatic symptoms were reported more frequently close to TMI compared to 41-55 miles away in April and July 1979 as well as in January 1980. However, by Oc tober,
4 1980, this difference was sharply reduced and the dif ference between the two groups was no longer statistically significant.
It should be noted that the general levels of symptom reporting fluctuated considerably over this time period.
This could have been due to many factors including seasonal variations.
Therefore, general levels of reporting are not necessarily indicators of the effects of TMI, while differences between the close and far groups are.
3.
Perceptions of TMI as a serious threat to one's family's safety came down over time for both the close and far groups, though, as with ratings of upset, the drop was sharper for respondents within 5 miles of TMI.
None theless, the differences between the close and far groups was still statistically significant in October, 1980.
4.
The attribution of symptoms to Three Mile Island, which involved o.
only respondents who reported behavioral or somatic symptoms, dropped sharply for both groups during the 15 months studied, but, as with perception of threat, attribution was still significant1v higher close to TMI in October, 1980.
The overall pattern of these findings shows reductions in distress for both the close and far groups over the 18 month period studied.
There was a sharper rate of reduction for the group close to TMI than far away.
Differences between the close and far groups persisted through October, 1980 for perceived threat and for attributed symptoms, but dropped to non-significance in October 1980 for ratings of upset and for number of persons reporting behavioral or somatic symptoms.

. ATTITUDES AND BEHAVIOR REGARDING THREE MILE ISLAND Two questions concerning Three Mile Island were repeated from earlier studies, allowing comparisons over time.
These will be discussed first.
The first question concerned restarting reactor number one, the undamaged reactor, at Ihree Mile Island.
Results, shown in Table 2 indicate that, in January, 1980, when the question was first asked, sixty percent of respon-dents close to TMI and thirty-one percent of respondents 41-55 miles away opposed re-starting the facility.
In October,1980, the percentages were much closer, with forty-seven percent of respondents within 5 miles of TMI opposing re-starting and forty-two percent of respondents livin 41-55 s
miles away opposing restarting. The difference between the two groups was statistically significant in January, 1980, but was not so in October, 1980.
It is interesting that both groups changed over time, but in opposite directions. Ilowever, when the changes of each group are tested statistically, the change close to TMI (from 60% to 47%) is statistically significant (X = 5.41, d rut,p <.05) but the change in the 41-55 mile group is not (X = 2.61, d f = 1,p >.05).
The second question repeated from earlier surveys concerned political activity and asked respondents whether they had, personally, been active in any organization or gone to any meeting to influence what happened at 1MI.
The results, shown in Table 3, indicate a slight increase from 13% to 15% among respondents within 5 miles of TMI and little change in the 41-55 mile group.
As explained in an earlier report (Houts et al,1980 part one) the participation rate near T?H is high by usual standards of political activity in this country.
However, it has not increased substantially in the nine month period f rom January 2
to October 1980, for either the group within 5 miles (x =.088, df=1, p >.05) or the group living between 41 and 55 miles away (X =.007, df=1, p
.05).

8 The remaining attitude questions had not been asked earlier and, therefore, data were only available for this survey.
The first group of questions dealt with how much influence respondents felt different groups should have in decisions to clean up TMI.
Respondents were asked if each of 8 groups should have "a lot" "some" or "no" influence in decisions to clean up TMI.
Respondents were scored 1 = a lot, 2 = some, 3 = none.
Don' t know responses were assigned mean values.
The 0-5 and 41-55 miles groups were compared utilizing analysis of covariance to control for age, sex, education, marital status and income.
Results, shown in Table 4, indicate a relatively high level of support for all groups.
Even the group with the lowest level of support, organized groups of citizens, received a mean value which indicated that they should have some influence.
It is interesting that the highest ratings were given to the Nuclear Regulatory Commission and to energy experts working for the l'ennsylvania Department of Environmental Resources (DER).
It appears that the public prefers technical experts working under government aus pices to have the most influence.
Respondents in both groups agreed rather closely in their ratings, though the DER was ranked signi ficant ly higher by persons in the 41 to 55 miles group.
However, it should be noted that both groups ranked the DER fi rs t.

10 Six attitude questions concerning belief in rumors were included in the October survey.
Each rumor had received publicity during or af ter the crisis.
Each rumor had also been shown to be either incorrect or else lacked objective verification.
Responses were on a four point scale with 4 indicating disbelief and I definite belief. An " undecided" response was given a score of 2.5.
The results, shown in Table 5, average close to 2.5.
It is interesting to note that all of the means for the group from 41 to 55 miles from TMI were below 2.5, while only three out of six means were below 2.5 for the group close to TMI.
Further, the two rumors where there was a statistically significant difference, (increased miscarriages, stillborns and infant deaths plus increased birth defects) showed greater acceptance of the rumors in the 41-55 mile group than in the 0-5 mile group.
This suggests the hypothesis that the group farther from TMI was more willing to accept rumors than the group close to TMI.
This hypothesis was tested by summing the six rumor scores for each respondent and testing whether the total rumor scores were different for the two groups.
The analysis of covariance test was not statistically significant, thus the hypothesis of a difference in general acceptance of rumors is rejected.
1 The final attitude question dealt with media coverage of the TMI situation.
Results, reported in Table 6, show that almost half of the respondents in 1
both groups felt that the media had blown events out of proportion, and one in five thought that information was withheld or covered up.
Less than one third felt that the events were reported accurately.
It is interesting that the two groups had almost identical percentages for each response option.

REACTIONS TO KRYPTON VENTING Three questions were included in the October survey which dealt with how respondents felt about the venting of Krypton gas at Three Mile Island a
in July of 1980. The venting of this gas had been the subject of considerable public debate in the months prior to its occurrence.
Partly as a result of this debate, the public was informed in advance of each venting.
This gave i
persons living in the area an opportunity to evacuate during venting periods l
if they so wished.
Data on who evacuated, when they left and for how long they stayed away was available for persons within five miles of TMI but not for the control group 41 to 55 miles away. Since the representative sample of persons living within 5 miles of TMI may have included some persons who l
moved into the area af ter the venting in July, 1979, estimates of evacuation may have been conservative. Results indicate that 15% of the population living within 5 miles of TMI in July, 1980 reported that the venting was an "important reason" I
.for their leaving and an additional 4% said that it was a "somewhat important reason" for their leaving during that period.
Furthe rmore, of those persons who 4
reported that the venting was at 1 cast a somewhat or very important reason for leaving, 40% lef t before the venting began, 52% lef t in the first week of ventin'g and 8% lef t in later weeks of venting.
The average length of absence due to venting was 10 days.
TVo atti tude questions about the Krypton venting were anked of respondents within 5 miles of TMI in October, 1980 as well as the control group from 41-55 miles away.
The results, shown in Table 7 are quite interesting.
For both questions, persons living close to TMI were significantly less negative about the venting than were people living f arther away.

15 CENERAL ATTITUDES Two questions dealt with general attitudes toward nuclear energy.
The first question asked how much scientists know about radiation and the second asked if there should be more, the same or fewer nuclear plants in the future.
The results, shown in Table 8, show no statistically significant dif ferences between the two groups on either question.
The averages for these questions indicate that the public tends to take a middle position on both issues.
Respondents perceived scientists as knowing between "something" and "a great deal" about radiation and they tend to favor the same number of nuclear plants in the future as now.

17 CONCLUSIONS These findings indicate that the number of people with serious concerns about Three Mile Island dropped substantially from January to October, 1980.
First, reductions were noted for both the 0-5 and the 41-55 mile group in:
Second, reductions were greatest in the 0-5 group and, as a result, the two groups became increasing similar over time in ratings of upset about TMI, perceived danger, reporting of stress-related symptoms and opposition to re-opening the nuclear facility.
It should be noted, however, that, in October, 1980, some distress indices were still significantly higher in the 0-5 mile group than in the 41-55 mile group.
These indices were perceived threat to safety and attribution of symptoms to TMI.
Attitude and opinion questions which were only included in the October survey showed relatively small dif ferences between respondents close to and far f rom TMI.
However, there were statistically significant di f ferences between these groups in attitudes toward Krypton venting and in belief in some rumors about negative ef fects of the crisis.
It is in teres ting that, for both types of questions people farther from the plant had more negative views than people close to the plant.
There was general agreement among persons both close to and far from TMI that the media had not reported the crisis objectively, that scientists know between "something" and "a great deal" about radiation and that technical experts working under government auspices should have the largest say in how TMI is cleaned up.
