Hours of
Operation: The Chief, Radiation Oncology shall establish the routine hours of the Radiation Oncology Clinic.
Services may be scheduled between 6:00 am and 6:00 pm Monday through Friday, excluding legal federal holidays, depending on patient treatment schedules. Machine warmup procedures will be dictated by patient schedule and can be as early as 5:00 am.
Normal routine clinic hours are 7:00 a.m. to 4:00 p.m., Monday through Friday. The contractor is responsible to ensure adequate staffing during operating hours. The total regular duty hours worked shall not exceed 40 hours per week. Duty hours include a one-hour lunch period, which is not paid by the government. Additionally, an on-call schedule will be maintained and staffed for any possible after-hours emergencies. The on-call schedule will be shared with the Chief of Radiation Oncology at least 30 days in advance. Any changes to this schedule will be immediately submitted to the Chief of Radiation Oncology. Additional overtime pay will not be paid by the government for hour accrued by any member of the Therapeutic Physics Contract Team. personnel under this contract are mission essential and inclement weather essential employees. Under mission essential and inclement weather conditions, the HCW will be required to continue the mission of the Radiation Oncology clinic unless properly released by an authorized government supervisor. Duties Provide all necessary dosimetry support for the aid of the treatment with the radiation oncologist, obtaining patients contours, registering different image sets sometimes with the aid of Velocity, determining the volumes to be treated, marking of the patient, and other routine services as required.
Participate with the radiation oncologist in localizing the volume to be treated, appropriately immobilize the patient, and provide dose distributions (isodose plans).
Verify treatment parameters (to include but not be limited to: field size, SSD/SAD, points of interest, dose per fraction, total dose, wedges, and blocks) by an independent calculation and enter such data on the bottom of the computer printout then sign it before placement in the patient's chart.
Provide treatment plan to the responsible radiation oncologist for approval before implementation.
Work with the radiation oncologist and medical physicist in planning LDR and HDR implant procedures, requests the sources, prepares them for use, loads the applicators, cuts the ribbons to the correct length, and is responsible for the safe use of the sources in compliance with the relevant regulations in respect to care, handling, record keeping and use of the radioactive material in the radiation therapy service.
