2.0 Test Objective To determine the ability of ElO Series Transmitters Standard Con struction both 4-20 and 10-50 mA output types to function during and after gama irradiation to a total dosage of 1 X lO7 rads.
3.0 Summary and Conclusions All transmitters functioned without failure to the total dosage of 1 x 107 rads.
The 4-20 mA output transmitters with the present standard amplifier (NO143XS) exhibited output shifts of less than 0.5%. Output shifts of the 4-20 mA output transmitters with prototype amplifier (NO148TE) and the 10-50 mA output units (standard amplifier N0143SY) were largely negative-going. Errors as high as -4.2% were noted.
Units with remote amplifiers had output shifts, zero shifts and span changes of less than 0.3%.
Zero shifts on units with integral amplifiers were comparable to out put shifts. Span changes were less than 1.5% up to the total dosage.
Performance tests performed in-house before and after irradiation showed little to no changes and were within published specifications.
Step response tests performed before and during irradiation indicated no effect due to irradiation.
4.0 Comments and Observations 4.1 All test data taken by the Foxboro personnel was initialed and dated by Mr. William McKimm or Mr. George Dietz of Isomedix, Inc.
4.2 Irradiation of the transmitters was interrupted at various times for removal of other items in the "hot cell". The periods of interrupt ion were recorded and time adjustments made for the scheduled dosage level checks.
4.3 The effect on the transmitter output of removing and replacing the radiation source was 0.1% or less at any time.
4.4 At a dosage level of 9.25 x 106 rads the dose rate was increased to 2 x 105 rads/hr to shorten test time. Results indicated no effect on transmitters by this action.
4.5 Visual examination of the transmitters found only a brownish dis coloration of the amplifier circuit board Conap conformal coating.

6.0 Test Procedure 6.1 Installation All eight test transmitters were mounted in a horizontal position through their normal mounting bracket to a vertical pipe stand.
The units were placed in a "V' pattern so they would be uniformily exposed to the radiation field. Placement of the specific trans mitters is in Diagram No. 1.
6.2 Monitoring All units were powered continuously and a 80% input signal was con tinuously applied except during calibration runs.
Outputs were recorded on a 4-channel recorder with a timing and switching circuit changing the four unit record every six hours.
Output current readings were read across precision resistors with a DVM at specific intervals.
See Figure No. 1 for schematic.
6.3 Irradiation Test With the units installed in the "hot cell" (cobalt - 60 source) and operating, initial calibration runs and a step response test (0 to 80%) were performed. The initial dose rate was 1 x 105 rads/hr up to a total dosage of 9.25 x 106 rads; at this point the rate was in creased to 2 x l05 rads/hr until the maximum total dosage of 1 x 107 rads.
At various dosage levels tests were performed to check transmitter performance. See Test Schedule #5 for specific test points and dosage levels.
6.4 Documentation All data runs taken were verified by personnel of Isomedix, Inc.
