Training
Thermoluminescent Dosimeters (TLDs)
TLDs are the primary method of monitoring personnel radiation exposure. They are issued in one of three colors.
RED - Issued to visitors and employees without training. Individuals wearing this badge must be escorted.
BLUE and YELLOW - Permanent TLDs issued to staff trained in Rad Worker I. Badge color is dependent on the month (even vs. odd-numbered months).
Need a Permanent or Temporary TLD?
- For staff requesting a Permanent TLD service, please contact C-AD Training. If C-AD Training is not available, please see Ken Boland, Joseph Vignola, or any RCT staff in building 923. Required training for TLDs includes Rad Worker I. If Rad Worker I cannot be completed before the desired date, the individual can take GERT and be escorted. They will be limited to areas not requiring Rad Worker I Training.
- For staff requesting a Temporary TLD, please either C-AD Training. If C-AD Training is not available, please see any RCT (Health Physics) staff. Staff will be directed to place their Temporary TLDs on the Temp TLD Board outside of room 128A every day.
- TLDs colors are changed each month, BLUE and YELLOW (odd vs even-numbered months)
Misplaced a Permanent TLD? Lost your TLD badge?
- Any RCT Techs can assist with misplaced TLDs. Temporary TLDs can be issued by C-AD Training.
TLD Exchange Weekend
- TLD exchange is usually done on the first weekend of every month unless there is a holiday. If a TLD is not placed on its assigned board in its assigned slot number, RCT staff will not place the new monthly TLD on the board. Instead, it will be placed on a separate, temporary board next to it or on the floor under the regular wall-mounted board.
- The temporary board will be available for one to two days after which they will be transferred either to the hallway floor next to the Training Office in Room 128A or placed on the whiteboard outside of the office. Locate the TLD you're looking for and replace it with the TLD that needs to be turned in for the month.
Do You Need a RED Visitor TLD for a Tour?
- Send inquiries to C-AD Training at C-ADTrainingGroup@bnl.gov for assistance. Please provide as much information as possible for the tour so that we can provide you with the correct paperwork that will need to be completed. Paperwork can be completed prior to coming to the C-AD Training Office, Rm. 128A, Building 911.
Returning RED Visitor TLD or Temporary TLD Visitor TLDs
- RED Visitor TLDs are normally used for one day. When the TLD is no longer needed, the visitor or BNL escort should place the RED TLD in the yellow box on the wall outside of the Training Office in Rm. 128A.
RHIC Access
Access Cards
Blue RHIC Access Cards
Contact the C-AD Training Group to request RHIC access card. Please note any special areas you will need access to and communicate this to the C-AD Training Group/Access Controls Group who will add it to your existing access list. The access card will be issued by Access Controls, Ext.7733, in Bldg. 911A, Rm 142.
Rad Worker I and CA Access Training is required. For Users that wish to access RHIC tunnels, GERT and Collider User Training may be sufficient. Please contact the Training Coordinator.
Pink RHIC Access Cards
PINK RHIC cards are usually for Experimental Users or for site employees who work in the same area as Users. Collider User Training and GERT are required. This applies to individuals who may need a BLUE RHIC card at times. STAR Users will also need to take STAR Low Hazard Trainer Trained Training and/or if they are going to be shift leaders.
Self-Reading Dosimeter (SRD)
During Limited Operations, anyone who needs an SRD should see Ken Boland or any HP Tech. If keeping the dosimeter long term, the SRD should be returned to Ken Boland or HP Techs in C-AD when they are due for calibration or if they are not working. Health Physics will then issue a new onw.
During Normal Operations, contact the C-AD Training Group who will issue SRDs as needed. Any SRDs that are due for calibration or are not working correctly should be returned to the Training Office, Room A-128, to be replaced with a new one (based on availability).
Oxygen Deficiency Hazard (ODH) Monitors
During Limited Operations: If an ODH monitor is needed, see Tony Curcio. If the Training Office (Room A-128) is open there is a sign out book on the file cabinet with ODH monitors next to it. Staff are requested to sign out the monitor they are taking by entering their life number, name, serial number of the monitor and calibration due date. Monitors that are out of calibration or not working should be returned to Tony Curcio or the Training Office.
Escape Packs
Contact Tracy Blydenburgh, Bldg. 911A , Rm. A-110 for details.
