SUMMARY
l "ASE0US RELEASES i
Radiation levels inthe environs resulting from the release of radioactive gases from the plant have been monit.ored since shortly af ter the event.
I Periodic, frequent radiation surveys have been and are continuing to be j
made both in the air and at ground level.. These surveys measure the radiation levels in the environs of the plant and the results are being used to assess the effect on the local populace.
The radioactivity in air which has been measured is principally noble gases-xenon isotopes.
Offsite air samples are being collected and analyzed by the NRC, 00E, Commonwealth of Pennsylvania and Metropolitan Edison Company at distances ranging out to 40 miles from the site.
Eight of the 147 samples have indicated concentrations of radiciodine
-13
-11 ranging frcm 2.7 x 10
- 2.4 x 10 microcuries/cc.
flo radiciodine was detected in the other samples.
The maximum activity detected is about one-fourth of the permissible concentration established in the NRC
" Standards for Protecticn Against Radiation," in Title 10, Code of Federal Regulations, Part 20 (10 CFR 20).
Analyses for radiciodine in several raw milk samples have yielded positive results, ranging from minimum detectable levels to 41 picocuries per liter.
The NRC has estimated the radiation dose to the thycoid of a child drinking milk with the highest reported concentrations of iodine to be less than 0.5 millirem per day. These sample results indicate levels slightly above normal background levels for radiciodine.
At 12,000 picocuries per liter the U.S. Department of Health, Education and Welfare recommends placing dairy herds on stored feed.
Local herds are already on stored feed because this is not the pasture seasca.
%.-q. o - 4 f-e.
AsJ
.h.'*.,
l The maximum radiation dose from the radioactive noble gases released has been cciculated on the basis of survey measurements. The dose to an invidid.
that could have occurred is estimatea to be less than the yearly expo
'e from natural ba:.kground levels of radiation. This estimate is
,ed on a hypothetical individual being present continuously at a point one-half mile northeast of the plant since the event began.
~
Offsite measurements have indicated significantly lower offsite exposures.
LIQUID RELEASES The discharge of contaminated water into the Susquehanna River has been and is being monitored frequently by the flRC, the Commonwealth of Pennsylvania and the State of Maryland.
Since March 30, there has been a controlled release of several hundred thousand gallons of water con-taining radioactive material. The discharge of this water has been stopped twice for further evaluation.
The instantaneous release limits for concentration of radioactive materials in water as allowed by the fiRC license may have been exceeded for short periods of time (a few hours) at the point of discharge into the river.
However, the limit established in the flRC license is somewhat more conservative than otherwise would be allowed under flRC regulations.
Although the limits were exceeded at the point of discharge, the calculated levels of radioactivity af ter dilution in the river indicate the concentra-tion would be a small fraction of the limits in NRC " Standards for Pro-tection Against Radiation" in Title 10, Code of Federal Regulations, Part 20 (10 CFR 20).
No radioactive iodine has been detected in the river water downstream frcm the plant.

NUCLEAR INCIDENT AT THREE MILE ISLAND Plant Status i
Reactor pressure remains near 1000 psi with bulk core coolant inlet and j
outlet temperatures approximately 280 degrees F.
Core thermocouple readings are relatively unchanged and indicate a maximum temperature of 452 degrees F which is well below saturation temperature for the present reactor pressure.
Three thermoccuple readi.,gs remain abova 400 degrees F.
The number of thermoccuple readings that are Leing monitored has been reduced to 30.
Containment atmosphere measurenants indicate. about 2% hydrogen.
One hydrogen recombiner is in operation, with another unit on standby.
A Heise pressure gauge has been installed to provida an alternate method of determining the pressurizer level by monitoring the steam space pressure and water space pressure in the pressurizer.
Testing procedures are under review.
The pressurizer is being vented
' the containment for about 15 minutes every 6-8 hours.
Plans for use of the robot to obtain a primary system sample have been developed.
Environmental Status Preliminary analysis by FDA of 16 milk and miscellaneous food products collected on April 3, 1979 sh0wed no detectable iodino concentrdtions in 12 samples and iodine ranging from 12-18 pCf /l in 4 milk samples.
The State of Maryland reported on April 4,1979 the results of analysis of 12 cilk samples collected frca 3 to 20 miles from the site.
All samples were repneted as less than the minimum datectabla activity (MDA).
One process milk simple from llarrisburg also was reported by ths Stata of Maryland as less than MDA.
Three water samples, two at Conswago and one from Holtwood Dam, were reportad as less than MDA by the State of Maryland.

One showed no detectable iodine and there are no results for the other two samples.
One of these samples shcwed a cesium concentration of 13 pCi/1; there are no costert results for the other four.
The State cf Pennsylvania analysis of 15 milk samples collected on April 3,1979 showed one with iodine at 19 pCi/1, 13 with no detectable iodine, and 1 with no result.
Four showad cesium levels ranging from 10-26 pCi/l and there are no results for the other 11 samples.
All of the samples collected by the State and FDA were split samples, i.e., shared to obtain independent results.
Continuous ground level radiaticn surveys performed on April 4,1979 by the NRC survey teams on the east and west si<ies of the suscuehanna River f ro.? a distanes of 4 miles north to 4 miles south of TMI showed radiation levels averaging less than 0.03 mR/hr on the east side of the river and 0.01 to 0.04 mPdhr on the west side of the river, Prevalent wind direction during.the day was from the east.
Six ARMS surveys were performed on April 4,1979 at:

The flights identified the plume to be in the sections of 200 and 300 The maximum radiation levels were detected during the 0600 flight during which levels of 1.2 mR/hr were detected using portable survey meters.
The 1522 fli0ht used normally installed ARMS instrumentation and measured radiation levels of about 0.1 nR/hr (about 5 times background) at 1 mile distance and about 0.05 cR/hr (about 3 times background) at 2 miles distance.
On April 4, a 40-minute air sample taken about 0100 near York !4 avan, and a 60-minute sample taken about 1300 in Goldsboro, both indicated less i
than 1 x 10 10 pct /ml I-131 (maximum permissible concentration for unrestricted areas).
Dose rates in populated areas as measured by NRC thermoluminescent dosimeters (TLDs) showed only minor changes from the previous day.
Minor fluctuations are expected at these low dose rates.

Occucational Radiation Excesures I
i Three occupational radiation doses in excess of the regulatory liait of 3 reos per calendar quarter have been confirr.ted.
All three exposures were licensee personnel and were approximately 4 re:as (this includes the two exposures reported in PriO-79-678).
To date on April 4,1979, there have been 12 individuals Vith doses greater than 2 rems but ler,s than 3 rems.
Three doses are for the period January 1 to April 4,1979, but it is believed the najority of exposure was received as a result of the incident.
More specific occupational exposure data is expected to be available in the near future.
Industrial Vaste Treatment system ( M S) i As of 0500 on April 5. 1979, the M S sump was 74% filled with about 100,000 gallons of capacity still available.
The State of Pennsylvania apprcved release of material feca the IWTS that does not exceed paraissible values.
No releases have been made as of 0500.
Other Information At about 5: 00 pm cn April 4.1979, the licensee initiated tha shipmant of solidified low level waste which was collected frca Unit 1 prior to the Unit 2 event of March 23, 1979. Additional shipments will be made twice daily.
The waste is being sent to the Chen fiuclear facility ir.
