R Qual Questions

TL D is required when entering

• Radiation Areas

• High Radiation Areas (HRA)

• Reactor Compartment (RC) after initial criticality

• When handling (RAM)

Why take SWIN actions

Prevent/minimize internal contamination your work maybe the cause of the airborne

What does win stand for?

• “Win” is used for response to any radiological problem

• Warn others

• Isolate the area/ item or immediately exit the area

• Notify Radcon

Procedure to transfer radioactive material (RAM)

3 T's

• Tagged with barcode RAMT (Radioactive Material Tag)

• Tracked using RAM computer system

• Transferred by RAM (Radioactive Material Controller) to the new destination

Examples of how to reduce exposure using distance

• Work at arm's length

• Adjust work away from hot spots

• Use remote equipment

A worker's control level can be increased by

Director of Radiological Controls

Phnsy's Local Exposure Control Levels

• R worker is 500 mrem/year

• Declared pregnant R worker 50 mrem/year

Difference between radiation and radioactive contamination:

• Radiation is energy emitted from radioactive material whereas

• Contamination is particles of radioactive material

Whole body frisk procedure

• Frisk hands first

• Frisk slowly ( 2” per second) / 2-3 minutes to do Frisk

• Pay special attention to FACT-B areas (Face Abdomen Chest Throat Back)

• Frisk within half inch of your body

• Frisk entire body

• Listen to audible response clicks on the instrument

• When finished, no error messages on display

When you hear an increase in the click rate while frisking:

Refrisk the area at a slower rate

If the frisker alarms

• Stand fast don't move

• Warn others in the risking area to stay away

• Notify the RCT

Why is it important that you keep track of your exposure?

To ensure you don't exceed Exposure Control Levels or NAVSEA limits

Tier 1 radiation level

Less than 30 mrem/hr

Equal to or greater than 30 mrem/hr with no gradients

Tier 1 dosimetry

Single TLD on chest

What is Tier 3 Radiation Level

Greater than 100 mrem/hr where gradient radiation fields exists

What is the Tier 3 Dosimetry?

Based on gradient surveys and engineering evaluation

EPD must be read

• Upon issue

• Prior to entering a High Radiation Area/RC

• Frequently while in the High Radiation Area to:

Whole Body Radiation Dose Limits

• 5 rem per year

• 500 mrem per term of pregnancy period

EPD is Required

• High Radiation Areas / Reactor Compartment after initial criticality

• Handling RAM with radiation levels greater than or equal to 100 mrem/hr

Effect of naval nuclear work on the environment

• No significant effect on environment

High radiation Areas must be

Guarded at all times
