Question 1

Four ionizing radiation hazards from the laser isotope separation of Uranium 235

Answer 1

X-ray produced from high-voltage power supplies

Airborne alpha and beta hazards exist during maintenance operations

Criticality concerns of highly enriched product - possible prompt gamma and neutron fields

Alpha/beta hazards exist from feed material and enriched product - surface contamination and potential ingestion hazards

Question 2

Engineering design features to minimize radiation hazards at a laser isotope separation facility

Answer 2

Proper shielding for x-ray hazards

Proper airflow and ventilation for alpha/beta airborne particles

Proper size and arrangement of transfer lines and storage containers will reduce the probability of a criticality accident

Air monitoring should be placed to warn of uranium dust

Criticality alarms

Glove boxes and fume hoods should be designed to facility ate chamber operations, maintenance and cleaning
