Generation time was varied by adjusting the volume airflow rate and the amount of aerosol placed in the generator.
More stringent measures to avoid cross-contamination are being examined for future experiments. Production data on cows.
Graphs of the 135-08 during the time of aerosol release are shown in Figures 5 and 6. These apparently contradictory observations imply that there might be some basic difference in the -way Group IV cows metabolized l 31I compared to the other groups. To measure in vivo the uptake of 31I in calves thyroids as a function of time.

At that time winds are generally from the north drainage winds at about mph with an inversion layer close to the ground.
FRC Report 5, Govt. The photograph to be examined is placed on the glass plate and a particle to be sized is centered over the iris image. Evans Introduction In an effort to formulate models for doses to human populations from fission-product releases, the Bioenvironmental Research Program is investigating the transmission of radioiodine through the Biosphere with particular emphasis on the milk chain portion of the human food chain.
This gives a measure of the half-life of the particulate activity. The four average temperatures for the period to are below: This evidence substantiates the different milk to grass ratios indicated above. It is assumed that this is because of the heavier deposition and larger particle size and that contamination, though present, was not observable. All data were recorded on IBM printout sheets and tally punch tape see Plate 5.
Each point of the adi is an average value of four daily analyses. There are differences in detail in these curves, though, which should be pointed out. Sudan grass samples were taken from the bases of the stakes by hand cutting all the grass above 10 cm in a 0. The samples were counted until a minimum of counts was achieved in the 0.
The large variation in percent decreases across the plot is not surprising since there was 31-08 large variation in the initial deposition of I.

The curve dropped rapidly for five days after the contaminated feeding was stopped so that the effective half-life during this time was less than one day.
In meeting the first objective, the activity per area basis was used because of the non-uniformity of density of the Sudan grass in the plot. The average inhalation exposure, using assumption 2is Such an additional small amount of 1 31I would not make any significant change in the observed results. Date and time of opening of tender—, 2 p. The smallest sieve available locally was Z50 mesh, so all the DE that passed through this sieve was used.
Thus, the average total J 31I single cow out-put was 5. A sample cal- culation is given below for Calf Soil and Grain Each of the soil and grain samples’was placed in a ml cottage cheese container which was covered and sealed.
Detailed specification will be issued along with the tender forms. Results obtained are presented in Table The contaminated spread and fresh green 3150-8 fed to cows led to similar 1 31I secretion in milk as indicated by the milk to grass activity zci of 0.
Comparison of temperature sensors. The apparent effective decay half-lives for the 3 I levels in the milk of the different groups of study cows were remarkably similar for the fresh green chop, spread green chop and hay fed cows. A recommendation for future exercises is to collect ad- ditional fallout samples at ground and at an intermediate level to allow for a better characterization of the aerosol cloud. Results of hay depth study. In meeting the second objective, the activity per weight basis was used because the sampling of grass, just before being fed to the cow, could only be done on a weight basis.
During the period between the two sets of samples two daysthe radionuclide decay of!
Data lor Group IV contaminated fresh green chop cows. Section 2 illustrates methods for presenting necessary design information through 50 oversized, fold-out drawings of highway and non-highway structures.
A dry aerosol was chosen because such a material may simulate close-in particulate fallout from a nuclear excavation experiment conducted in a desert environment. The results of the milk data are tabulated in Table 27 and the 315-008 are plotted in Figure
