Study Notes
Radiation Exposures
- Acute radiation exposures involve large doses received over a short time.
- Chronic radiation exposures refer to small doses spread over an extended period.
Radioactive Decay and Isotopes
- Radioactive decay results in radiation emitted from an unstable nucleus of an element.
- Isotopes are variations of an element differing in neutron count but having the same number of protons.
Safety and Transportation of Gauges
- Nuclear gauges are classified under hazard class 7.
- Secure gauges by blocking and bracing only in designated areas, like the trunk of a vehicle.
- Two Yellow II Radioactive Labels are required on each gauge case during transport.
- Essential documents while transporting a gauge include an emergency response sheet and a bill of lading.
Radiation Types and Shielding
- Alpha radiation is the least penetrating type of radiation; effective shields include paper or skin.
- Neutron radiation can be shielded effectively using materials like plastic.
- Gamma rays require dense materials such as lead for protection.
- Alpha and beta radiations never escape the shielding in the gauge.
Measurement and Monitoring
- The strength of radioactive material is measured in curies or becquerels.
- A TLD (Thermoluminescent Dosimeter) or film badge is essential for monitoring radiation exposure.
- The Transport Index indicates the maximum dose rate at one meter from the package.
Regulations and Training
- Regulatory enforcement comes from the NRC, U.S.D.O.T, EPA, and Agreement States.
- HAZMAT training is mandatory for individuals handling radioactive materials while certain roles may not require it (e.g., accountant).
- Training for gauge operators is mandatory to ensure safe handling practices.
Dosimetry and Exposure Limits
- A pregnant worker's radiation exposure limit is typically set at 500 millirem.
- The time it takes for a radioactive material to decay to half of its original activity is termed the half-life.
Emergency Procedures and Compliance
- If a gauge is lost or stolen, immediately report to the RSO and regulatory agency.
- In case of a gauge tip-over, check for damage before resuming work.
Miscellaneous Safety Practices
- Do not store batteries in gauges during periods of inactivity to prevent potential issues.
- Always adhere to facility regulations and ensure radiological signage is posted in the storage areas.
Disposal and Age Limits
- Disposal of gauges over 20 years old should follow proper protocols rather than common disposal methods.
- New workers cannot operate gauges without proper training, even for limited periods.
Key Concepts
- "ALARA" stands for "As Low As Reasonably Achievable," emphasizing minimization of unnecessary radiation exposure.
- Background radiation exposure does not count as occupational exposure.
