2. HAZARDS IDENTIFICATION
Radiological Hazard
Warning: THIS MATERIAL SHOULD ONLY BE USED BY PERSONS QUALIFIED TO HANDLE
RADIOACTIVE MATERIAL!
This product contains licensed radioactive material and is therefore subject to the requirements of 10 CFR Part 20
(e.g., public and occupational exposure limits, waste disposal). At a minimum, the basic radiation safety principles
of time, distance, and shielding, and appropriate radiation contamination control should be practiced to
avoid/minimize any external and/or internal exposure. Consult with your Radiation Safety office for your facility’s
radiation safety requirements/precautions specific to the radionuclide(s) (including its activity and chemical/physical
form) in this Radioactive SRM.
SRM 4427L is a radioactive material, yttrium-90, with a total activity of approximately 5 MBq in a
hydrochloric acid solution. Yttrium-90 decays by beta-particle emission. During the decay process, X-Rays
and gamma rays with energies from approximately 2 keV to 2.2 MeV are emitted. In addition, the beta
particles emitted from yttrium-90 produce bremsstrahlung photons with energies up to 2.3 MeV. THIS SRM
SHOULD ONLY BE USED BY PERSONS QUALIFIED TO HANDLE RADIOACTIVE MATERIAL!
