Iridium – 192
Iridium 192 emits
extremely high energetic gamma/beta radiation.
The principal photon energies for gamma emissions are at 0.468 MeV (80%)
and 0.317 MeV (49%) while beta emissions are at 0.670 MeV maximum. Iridium –
192 has a half life of 74 days. One
curie of Iridium – 192 will give
a dose rate of 480mR per hour at a meter.
Iridium – 192 labeled compounds have both internal and external exposure hazards to humans. Internally, Iridium – 192 can cause localized damage if inhaled, ingested, or absorbed by the skin. Externally, both gamma and beta radiation will cause damage to exposed areas.
Certain precautions can be taken to ensure
that radiation exposure is kept to a minimum:
Minimize the time spent in close
proximity to the radioactive materials.
Always use remote handling tools such as
tongs whenever handling radioactive material.
Use radioactive materials in
If necessary, shield the radioactive
materials such that radiation dose rates are less that 0.25 mR/h in accessible
Always wear disposable gloves and/or
clothing whenever handling radioactive materials and keep your hands away
from your mouth or other exposed skin.
Always monitor yourself and areas where
radioactive materials are used for loose contamination and remove if detected.
The Canadian Nuclear Safety Commission must be contacted within twenty-four (24) hours of a loss of radioactive sources or of an accident/incident that could result in a personnel exposure in excess of the limits detailed in Schedule II of the Atomic Energy Control Act.
