F999--636-26-3-1048-0031 - Landauer Dosimetry - NWI (VA-26-00058924)

Answers to Technical Questions

1. What was the total value of the most recent dosimetry services contract for the NWI HCS (i.e., the predecessor contract to this requirement)?

The predecessor contract was a Firm Fixed Price contract with flawed pricing prompting this requirement to be resolicited as an Indefinite Delivery Indefinite Quantity (IDIQ) contract.

2. What is the expected total number of program participants (badge wearers) across all three locations Omaha (OVAMC), Lincoln (LVAMC), and Grand Island (GIVAMC)? The SOW references approximately 150 dosimeter badges; can you confirm whether this figure includes all badge types across all sites? There is a need for approximately 200 badges across all sites.

3. What is the expected number of Whole-Body dosimeters needed monthly?

150

4. What is the expected number of neutron-capable dosimeters needed monthly?

Zero, our current license scope does not require this type of monitoring.

5. What is the expected number of extremity rings needed monthly?

5

6. Is there an estimate of the number of unreturned dosimeters per month, based on historical experience? This information will assist in accurate pricing for replacement badges.

10

7. Are return postage-paid shipping labels required under this contract, or does the Government handle return shipping?

Yes, we require postage paid shipping labels

8. Is emergency dosimeter processing and analysis (within 24 hours of receipt) required under this contract? If so, should the cost of emergency processing be included in the monthly unit pricing, or priced as a separate line item?

Yes, emergency processing should be included as a separate line item

Statement of Work

NWIHCS Imaging

Radiation Dosimetry Contract

Background: Provide radiation safety badges (dosimeters) to NWIHCS employees who are exposed to radiation as a function of their employment, as well as environment monitors for specified areas of NWIHCS buildings that contain equipment which emits radiation.

Purpose of Project: To establish objective, technically defensible evaluation criteria for occupational radiation dosimetry services supporting a federal medical facility with extensive fluoroscopic, nuclear medicine, and research operations.

We currently order dosimeters through Landauer. We enter a 2237 to obligate the funds and then pay for them on a credit card out of FCP 023 when we are invoiced quarterly. We would like to streamline the ordering and invoicing process through the utilization of a contract.

Statement of Work

Description of Work: Contractor will provide dosimeters to all employees who are exposed to radiation as a function of their employment and for specified areas of the hospital requiring monitoring outlined by the Radiation Safety Officer. Frequency of monitoring will be quarterly or monthly as determined by Radiation Safety Officer and contractor will provide each monitor as ordered. Contractor will provide individual radiation dose reports from said dosimeters.

Schedule of Deliverables:

Period of Performance: 07/01/2026 07/01/2027

With option years 1, 2, 3, and 4

Description of Tasks and Associated Deliverables: Provide personal whole-body and extremity dosimetry badges as well as area monitoring badges and radiation dosimetry reports per Radiation Safety Officer weighted technical evaluation criteria.

Reports: Web-based portal availability to dosimetry reports.

Contractor Qualifications: Provide dosimeters meeting the regulatory rerequirements established in Title 10, of the Code of Federal Regulations, Part 20, Standards for Protection against Radiation (10 CFR Part 20) (Ref. 1), which requires licensees to determine and record occupational exposures to demonstrate compliance with dose limits for adults (including declared pregnant women), an embryo/fetus, and minors and to supply and direct the use of individual monitoring devices.

Hold current NVLAP accreditation for:

Whole-body dosimeters

Extremity dosimeters

Meet all applicable portions of:

ANSI N13 Series

ISO/IEC 62387 Standards

Evaluation and Award Factors:

Specialized skills, expertise, knowledge: Ability to detect and report as little as 1 millirem of radiation exposure, multi-element filter packs within OSL technology that allows for re-readability as well as discrimination of radiation energy and type (as explained in market research) and provide Multiple Employer Total Exposure Reports (METER).

Low-Dose Performance (Whole-Body Dosimetry) High Weight

Minimum detectable dose

Minimum reportable dose

Ability to report and trend doses 1 mrem

Impact on ALARA tracking for low dose, high-frequency exposure groups

Rationale: Low-dose sensitivity is critical for fluoroscopy staff, physicians, and long-term cumulative exposure assessment.

Extremity Dosimetry Accuracy & Robustness High Weight

Detector technology (TLD vs. OSL)

Sensitivity at Hp(0.07)

Angular and energy response

Reliance on declared radiation field assumptions

Ability to adapt to changing clinical practice without loss of accuracy is dose reporting

Rationale: Extremity doses are among the most frequently challenged and scrutinized in medical radiation protection programs.

Energy Discrimination & Radiation Differentiation High Weight

Ability to distinguish:

Photon energies across diagnostic ranges

Beta vs. photon exposure

Mixed-field performance

Algorithmic correction methods

Rationale: Medcal radiation fields are rarely monoenergetic or static.

Dosimeter Re-read Capability & Data Integrity Moderate to High Weight

Ability to re-read dosimeters

Demonstrated signal stability

Validated correction factors for repeated reads

Documentation supporting forensic dose reconstruction

Radiation Dose Investigation & Adjudication Support High Weight

Formal investigation workflows

ALARA exceedance analysis

Historical dose comparison

Expert technical support during:

NRC (Nuclear Regulatory Commission) inquiries

Worker compensation cases

Legal challenges

Institutional Experience in Federal Medical Settings Moderate Weight

Demonstrated experience supporting:

VA facilities

Academic medical centers

Long-term occupational dose records

Continuity with historical dose methodologies
