Serum protein values for Hayseed cows. Plots of the weather, G-M, and scintillator count-rates during the release are included at the end of this section. It would appear that the I is less biologically available to dairy cows when it is on spread and fresh green chop than when on hay. Sealed tenders are invited for the supply of various items to Mechanical Engineering Department of Rajiv Gandhi Institute of Technology, Kottayam at a total cost of ‘ 1,76, Horizontal length mm max.
The release of all the aerosol required approximately 30 minutes because the generators were turned off when the wind veered too far in one direction and because the cai -was fairly high.
Average milk values obtained for the controlled I ingestion studies. Considerable success was attained acu contaminating the forage in this fashion. Wind speed and direction. The results of the milk data are tabulated in Table 27 and the values are plotted in Figure The dose rate on the backs of the inhalation cows averaged two times that on their legs indicating a low lying aerosol cloud which was approximately Z to 3 feet high as it entered the measured area.
They -were fed eight pounds 3. If one 31-08 the amount of milk produced by the cow having the maximum 1 31I concentration in its milk to the amount of milk produced by the cow having the minimum 1 31I concentration for each milking an interesting qualitative finding emerges.
Conclusions Results indicate that some recontamination of the field took place during each irrigation. This type of calculation assumes that most of the uptake occurs by 24 hours after ingestion and treats all previously ingested radioiodine as if it were given as a single dose 24 hours before xci thyroid measurement.
The slight variation in 3315-08 direction probably aided the experiment by causing mixing of the 10 aerosol streams resulting in a more uniform deposition. The peak daily average values of 1 3 ll activity in milk were 4 4 2. The table includes the quantity of hay consumed by the individual cows and the total l 3 11 activity per daily feeding. All sizing was subsequently performed on photomicrographs representing magnifications of and The present meterological tower height of 10 meters ack sufficient for measurement of strong inversions over green crops with the existing system.

It is clear, however, that such artificial systems for obtaining contamina- tion must be related to more realistic systems before we will be able to completely interpret and evaluate the data obtained from Palanquin. Fifteen samples from each stack were collected following the aerosol release. Filters were changed and the collected filters transported to Las Vegas for counting. Even if allowance is made for the difference in effective half-lives in the milk, 315-008. Measurements of the total combined depositions on growing Sudan grass, spread hay and spread Sudan green chop accounted for The hay and green chop samples were not related to an area measurement, but were correlated with the other data on a per unit mass basis.
Air Sampling The air sampler operated by Team 5 adi and cut off after running about six minutes. The filter papers and fall out trays were then removed from their sealed environment.
The true change in activity caused by the cutting and transportation process, is undeterminable at this time due to a lack afi sup- porting soil and vegetation data.
Figure 34 breaks this box down into two sections called “Particulate Sampler” and “Gaseous Sampler”. Total pCi 1 31I in thyroid calf study.

The second trial agrees with this trend which appears to be caused by the change in humidity as the day progressed. The major purpose of Project Hayseed was to relate our artificial systems for obtaining contamination to a more realistic system when the contaminant is a synthetic, dry aerosol tagged with 1 31I. Supporting this is the fact that the group 1 and group 2 photographs give data which compare favorably to data achieved by visual sizing in which no particles below 2u were included.
From the particle size test, it appeared that much of the heavier material fell out in the first few feet. The uppermost figure represents the top layer, the middle figure represents the second layer, and the bottom figure, the third layer. Test three commenced at at which time the winds had reversed in direction and were variable out of the south from 3 to 6 mph with gusts to 12 mph.
Russian thistle is an annual. Thus, for the experimental conditions of this study, the FRC estimates are quite conservative. To fill the bin, it was necessary to wheel it to a storehouse approxi- mately 50 feet from the milking stanchions.
Also, a ground level sample may better represent the deposition on the field and would lend itself to depo- sition velocity calculations. One ml round-bottom flask was used in generating an untagged aerosol in an atmosphere that approached quiescence. The filter papers were held in place on a 5″ planchet by double edged masking tape.
