Radioactive Waste Management and Processing
Make and maintain control with all relevant persons involved with radioactive waste to provide an authoritative point of advice and guidance, Establish and maintain a detail record keeping system for all stages of radioactive waste management, including the inventory of radioactive waste, Ensure that waste package for off- site transportation is prepared to be in compliance with Transport Regulations, Ensure that appropriate shielding, labeling, physical security and integrity of waste packages, Segregation, collection and characterization of radioactive waste, Treatment and conditioning of radioactive waste.
Organizational structure of ERPA
The solid organazational structural unit of ERPA. ERPA is a Federal Government body that control and regulate the import,export, use, transport, dispose of, etc any source of radiation.
WHAT IS DOSIMETRY?
WHAT IS DOSIMETRY?
Dosimeter is the act of measuring or estimating radiation doses and assigning those doses to individuals. The Radiation Protection Authority set requirement for radiation workers to ascertain their doses.
There are two types of radiation exposure
- External exposure: - which occurs when the radiation source or nuclear substance is outside of the body.
- Internal exposure: - which occurs when the radiation is emitted by nuclear substances inside the body.
Three methods are commonly used to determine radiation doses to humans:
- personal dosimetry
- indirect monitoring using measured dose rates or airborne concentrations of nuclear substances; and
- indirect monitoring using environmental pathways analysis
Personal Radiation Dosimeter
Personal dosimetry is used primarily to ascertain doses to workers in the radiation and nuclear industry. External exposures are typically monitored by the use of small radiation detectors called dosimeters, which are worn on the person. Internal exposures are typically monitored by measuring the presence of radioactive or nuclear substances in the body, or by measuring nuclear substances excreted by the body.
What does the dosimeter do?
A radiation dosimeter or badge does not provide protection but detects and measures radiation that you have been exposed to. The badge will detect high-energy beta, gamma or x-ray radiation. Dosimeters cannot detect low energy beta radiation from some isotopes, including carbon-14, tritium or sulfur-35.
What types of dosimeters are there?
Currently there are two types’ badges, Optically Stimulated Luminescence (OSL) by DOSIMED dosimeter service and TLDs (thermo luminescent dosimeter) provided by Ethiopia conformity Assessment enterprise. The OSL and TLD badge measures whole body and extremity (finger, hands etc.) dose from x-radiation, gamma radiation and beta radiation.
Who needs a dosimeter?
Radiation workers who operate x-ray machines, flouroscopy units, certain unsealed and sealed radioisotopes or are exposed to other sources of gamma or high energy beta radiation are generally required to wear one or more dosimeters.
