(c) set of source drawer handling tools (see dwg. #A1024 25 001). (d) hydraulic lift truck for moving source transfer shipping container. (e) source container fitted with one dummy. filler drawer and fire shield (if a shipment or source storage is planned).

3. - Both persons shall wear a 0 - 50 m/r/hr and a 0 - 5 r/hr pocket dosimeters - correctly zerced, together with an A.E.C.L. film badge.

4. - Prior to commencement, the authorized person shall: (a) perform a survey of the shipping container to ensure the levels observed agree with those on the shipping documents. (b) make a survey of those areas from which uncontrolled persons may have to be evacuated in the event of a maltransfer. Any area in which the radiation field is 5 m/r/hr or '" greater will be considered as a " Controlled Area". - . . _ . .. -. .- . . .. ------.. - - .. .. -

- 2- 1 ' .

s SECTION A: GENERAL - Cont'd (c) have readily available the telephone number, contact officer, etc., of the nearest office of the official Atomic Energy Control Authority in the area in which the transfer is to take place. (d) have similar information at hand if immediate assistance is required from: -i) The. Municipal Police Department

| ii) The Municipal Fire. Department

, iii) The Civil Defence Department NOTE: (1) In the event of a maltransfer, do not depend on locked doors to secure the " Controlled Area". See that guards are posted to prevent entrance to the " Area".

1 (2) Report to A.E.C.L. Radiation Hazards Section immediately after all entrances to the " Controlled Area" have been secured. - -

/ SECTION B: PREPARATION !

1. - Ensure that the source is in the "0FF" or ' ) storage position then, enter the treatment' room i and place the radiation survey meter in the . working area. The meter must be in the " ACTIVATE" l or "0N" condition at all times while this operation is'in progress. c 2. - Operate the head vertical travel to a convenient | working level and the head rotation to its zero e lock position.

3. - Close collimator to minimum opening and remove all source head and neck covers. Wipe test the collimator leaves for any indication of removable contamination.

4 - Remove power from the unit by means of the key switch on the control unit. DO NOT RELEASE THE AIR PRESSURE FROM THE STORAGE RESERVOIR.

5. - .By means of the hydraulic lift truck, position the transfer case in line with the therapy head, with approximately one (1) foot separation. Close ' collimator to minimum opening.

Wipe test both ends of the drawers and check , ; for any removable contamination. ! l j 7. - Remove front bracket assembly,. light housing J j assembly and front connecting plate (illustrated ; in Figure 5-7 in the Service Manual) . i - : 8. Carefully move the transfer case toward the therapy 1 i head (correcting any misalignment during the process) | until the large register on the transfer case - engages with the machined. boss on the therapy head. k 9. - Ensure that all passageways above, below and at both sides are evacuated so that there is no j possibility of others receiving exposure as a C; | result of the transfer. Very carefully mate the i source container with the unit head, there is a spigot on head and a recess on the container for this ! ; purpose.

I 10. - - Place the survey meter on the floor in such a - 1 ~ position that it is not subjected to the direct * ' # radiation field during transfer, but is accessible from behind the container. Use the 0 - 10 r/hr scale. ;

11. - Block between the source container'and the' floor as ; ' t- a safety precaution.

SECTION C: SOURCE REMOVAL [ 1. - Ascertain that the electrical power is still off.

|- ? - Check that the radiation' meter is "0N", dosimeters ; are zerced, and film badges are worn.

|' 3. - Insert the "T" rod source handlers tool through the hole in the center of the filler or dummy drawer in the container and thread it firmly into j the source drawer in the~ head. : ~ 4. - The assistant will disconnect the auxiliary retractor ; rod followed by, the removal of the cylinder connecting rod shaft to the source drawer connecting : rod assy. lie will then likewise take up a position- # behind the source container.

s SECYION C: SOURCE REMOVAL I | - ! 5. The authorized person will by means of the

"T" bar, gently draw the source drawer forward , approximately two to three inches. Ile will then ) rotate the drawer in a clockwise direction , 90 and continue to draw the drawer forward until ! it butts against the dummy or filler drawer. i l At this stage the assistant will take a position whereby he can support the weight of the dummy /

filler drawer as it emerges from this case. i i The authorized person will then continue to draw the source drawer forward until it is completely in the container. lie will then unthread the "T" bar and withdraw it from the filler / dummy drawer. 1

6. - Carefully remove the air cylinder connecting rod and plate assembly from the opposite end of the source drawer. Put the container rear cover plate in place and secure.

m. 7. - Move the container forward and install the other , ,, cover plate.

8. - Store the filler / dummy drawer and the air cylinder and plate assembly in a safe place.

9. - Place the source container in a convenient locatica in the room, as remote as possible from the working

area. Make sure that the Radiation Warning signs | are readily visible.

- 10. Proceed with the major servicing of the unit i (if applicable). j

SECTION D: SOURCE INSTALLATION

- General before proceeding further. . 1. Review Section A:

2. - Operate the head to a vertical position close to the lower limit of travel.

3. - Position the transfer case in line with the therapy c head. Open one cover plate on the case to deternine j the correct orientation to the head, i.e. that when the registers on the case and the therapy head r are mated, the new source drawer will be aligned ., with the bore in the head.

_ ontainer toward the head one (1) inch. The ~- .ssistant will now support the filler / dummy drawer in line with the new source drawer and the authorized person will insert the "T" bar' through the filler / dummy drawer and thread it into the line source drawer. The assistant can now insert the end of the dummy / filler drawer into the one (1) inch spa:e until it butts to the live source drawer.

12. - The authorized person will then push the dummy / filler drawer into the source container until it is fully entered then, immediately, gently push the "T" bar until the live source drawer comes tc a stop against the air cylinder shaft in the therapy head.

13. - Af ter noting that the survey meter indicates a safe condition, the assistant will take a position where he can observe the orientation , of' the slot in the source drawer connecting rod to the mating section on the end of the air cylinder piston shaf t.

19. - Survey the head and complete the Head Survey forms in duplicate. This survey is not to be construed as an official survey for licensing purposes but only to make reasonably certain that the radiation leakage levels are within permissible tolerances.

20. - With the treatment room door closed, operate the shutter to the "0N" position and then open~the treatment room door just enough to energize the door inter 1cck switch and note (1) that the shutter closes immediately and that the reset button must be operated before the 11, shutter will open again - repeat at least five (5) times.
