## Introduction

- Perspective- Acknowledge differences in federal business versus private business
- 10 CFR 835 (DOE) versus 10 CFR 20 (NRC)
- Core requirements and needs are the same
- Merging of four companies with different Radiation Protection Programs (RPP) and philosophies
- Build program from ground up
- Keep simple but effective and efficient
- Add metrics as needed
- Prevent “analysis paralysis”

## What is a metric?

- A metric is simply a performance indicator(s) established to monitor, to trend, to _proactively_ identify problems and to _determine the effectiveness_ of each license, facility or project’s RPP (organization).
- Each metric value for each organization is established by that organization with oversight and continuity by “Corporate (Headquarters).”

## Corporate Specific Radiation Safety Metrics

- 1) Collective Total Effective Dose Equivalent (TEDE), and
- 2) Maximum individual TEDE, and
- 3) Average TEDE (dose greater than zero), and
- 4) Personnel Contamination Events (PCE’s)
- Sub-Tier organization have more restrictive limits

## Collective TEDE

- Total person-rem for organization
- TEDE = External Dose + Internal Dose

## Maximum Individual TEDE

- Highest individual dose
- Organization establishes goal at beginning of year or partial year for specific project

## Average TEDE

- Only for individuals that receive dose
- Collective Dose/number of workers with dose > zero

## PCE’s

- Contamination, above limits, on anything other than PPE (i.e. hair, skin, personal clothing)
- _Major_ indicator of RPP health (adequacy of training, surveys, PPE, RWP’s, RadCon techs, etc)
- Use Statistical Process Control (SPC)
- Steven Prevette, Hanford
- DOE’s Integrated Safety Management (ISM)

## Radiation Safety Committee (RSC)

- 	Each organization resulting in occupational radiation dose (greater than 100 mrem TEDE (1.0 mSv)), shall maintain an RSC to ensure appropriate review of radiological concerns and metrics. The RSC shall consist of the RSO, as Chairperson, facility or project management representative(s), representatives of the various Operations and Maintenance groups at the facility or project, and other individuals with appropriate technical expertise as deemed necessary by the Chairperson. At a minimum, the RSC will meet quarterly.

## RSC (cont.)

- The objectives of the RSC are:
- 	1.	Ensure that Corporate (Headquarters) radiation safety 	commitments and regulatory requirements are integrated 	into all appropriate work activities; and
- 	2.	ALARA Program oversight, _including approval of _	_specific facility, license or project-performance goals and _	_metrics_; and
- 	 3.	Review of proposed programs, operations, and licensed 	facilities and projects where radiation or radioactive 	materials are involved.

## Reports

- Monthly or appropriate frequency to senior management
- Keep simple

## Radiation Safety Dashboard

## Use of Metrics

- Reviewed at appropriate frequency and compared collectively
- _Proactive_ management versus _reactive_
- Compare year-to-year
- Compare between organizations
- Used for proposals

## Use of Metrics (cont.)

- Use of common “tools” to ensure metrics can be properly compared (i.e. OSL’s vs TLD’s)
- Independent assessments to gauge performance and help standardize approaches
