RadCon Field Logbook

 * Quick and accurate accounts of shift activities
 * Permanent legal records
 * Allows quick and easy access to notable changes in rad conditions
 * RCT RadCon Field Logbook responsibilities
 * RCT should review previous 25 hours after shift change
 * RCT should initial after their review
 * Allows tracking to be easily performed
 * Maintain and control loose-leaf logs in same manner as bound logs

Logbook entry info

 * Resp protection requirements
 * Status of ongoing jobs for shift change
 * out of date instruments
 * Follow up actions and correction actions
 * Safety issues and RWP changes
 * Rad posting actions
 * Delinquent routine surveys
 * Reports of abnormal events

Denoting actions or special attention

 * Identify name of person leaving instructions
 * Use left margin to mark items requiring follow up attention
 * Identify date and shift
 * Identify manager notified
 * Record survey number
 * Identify action taken

Examples of actions needed

 * Off normal situations
 * Reportable events
 * Unsafe conditions need immediate action
 * Potential contamination spread or over exposure
 * Inoperable or questionable equipment
 * Items of notable importance needed follow up action, even if non-radiological

Hold point criteria
=Comm Systems (X)=

Importance of comm systems

 * Used to quickly and effectively allow information sharing across the site for basic needs and emergencies

Comm types

 * Public address systems: includes loud speakers and calling stations
 * Telephones: Employees work phones and landline phones
 * Pagers: personal pagers can be provides to employees away from the facility paging system
 * Radios: portable radios allow effective mobile communications
 * Email: employees can receive various updates and communications thru their email access

Do's and Don'ts

 * Improper language
 * Willful damage of equipment
 * Interference of communications
 * Release information without proper authorization
 * Unneeded communications
 * Alter equipment without authorization
 * Transmission of wrong callsigns
 * Rebroadcast other transmissions

Good comm attributes

 * Minimize usage of shorthands
 * Make instructions clear
 * Make sure speakers are properly identified
 * Use proper terminology, avoid slang and similar sounding words
 * Repeat messages, 3-way communication
 * Speak clearly
 * Acknowledge communications

Basic comm requirements

 * Give instructions using well understood terms and expressions
 * Use phonetics when needed to avoid misinterpretation
 * Directions clearly stated
 * Communicate identity, location, needs, and pertinent information
 * Hold radio or phone appropriately close to be clearly heard
 * Speak slowly and in a normal tone
 * Verbal instructions can be supplemented with written guidance for ease of remembrance
 * If worker believes they may be unable to follow all instructions, communicate to management or the person who gave instructions
 * Sender and receiver identifications needed before giving messages
 * When using radio, make sure airway is clear, do not interrupt, use unit number, keep brief
 * If no response, call twice only and then move on

=Count Errors and Stats=

=Dosimetry=

Dosimetry terms

 * Absorbed Dose: Energy imparted by radiation per unit mass, uses Rad or Gray
 * Radiation Weigh Factor: Modify dose calculations according to target organ or tissue
 * Equivalent Dose: Product of Absorbed Dose X Rad Weight Factor, uses Rem or Seivert
 * Whole body=1cm; Eye lens=.3 cm; Extremity or skin=.007cm
 * Whole Body: Head, torso and male genetals, arms at/above elbow, legs at/above knee
 * Extremity: Feet and legs below knee, arms and hands below elbow
 * Effective Dose: Sum of Equivalent Dose and appropriate Rad Weight Factor
 * Committed Dose Equivalent: Equivalent Dose to be recieved by tissue or organ over 50yr period after radionuclide intake
 * Tissue Weight Factor: Overall ealth risk according to exposure specific to each body part
 * Committed Effective Dose: Sum of CDE multiplied by Tissue Weight Factor
 * Total Effective Dose: Sum of Effective Dose for external and Committed Effective Dose for internal
 * Cumulative Total Effective Dose: Sum of TED for an individual for each year of DOE employment
 * Annual Limit on Intake: Amount of radionuclide inhaled/ingested by average adult on yearly basis, 5R CDE or 50R CED
 * Derived Air Concentration: ALI of average worked over 2000hr work year, measured in DAC/hrs
 * Bioassay: Determination and measurement of rad material in the human body
 * In Vivo: Bioassay measurement of rad matter in living tissue, whole body or chest count
 * In Vitro: Representative samples of rad material in human body, such as urine or fecal samples
 * Background: Natural radiation existing in environment
 * Declared Pregnant Worked: Woman who has declared pregnancy to her employer in writing and subject to occupational dose limits appropriate to pregnant workers

Exposure limits DOE

 * Gen employee: Whole body 5R; Eye lens 15R; All other 50R
 * Declared pregnant worker: 500mR
 * Minors occupational exposure: Whole body 100mR; all other 10% of general employee limits

=Contam Control=

=Air Sample Program and Methods=

=Resp Protect=

Respirators and limitations

 * Air purifying particulate: Negative pressure; powered air purifying respirators use positive pressure

Respirator protection hazard considerations
=Rad Source Control=

Container integrity testing and leaking sources
=Enviro Monitor (X)=

Overall

 * Detect and quantify unplanned release
 * Meet legal and regulatory requirements
 * Site Monitor Programs
 * Air: continued sampling of air particles in a location, typical 2wk at first then 6mo
 * Water: Above ground water sources/1 liter
 * Soil: Contamination taken in by ground soil; used well defined depths, areas, and quantities
 * Vegetation: Main methods are clippings and core samples
 * Ambient: Measured using TLD on and off site

Genpop exposure limits

 * Exposure to public from rad sources
 * Shall not exceed a TED more than 100 mR
 * Includes external exposure sources and consumed radionuclides

Critical nuclide/pathway

 * Critical nuclide: Nuclides that cause significant offsite dosage
 * Critical pathway: Path taken by a radionuclide to enter a human body
