SECTION 2: Hazards identification
NFPA Ratings
(Scale 0-4) Health = 3 Fire = 0 Reactivity = 0 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 4949c is a radioactive material, Iodine-129, with a massic activity of 3451 Bq•g-1 in a sodium hydroxide and sodium sulphite solution. Iodine-129 decays by beta-particle emission. During the decay process X-rays and gamma rays, with energies from 4 keV to 40 keV are emitted.
Health hazards
There are no major chemical health hazards associated with this sodium hydroxide/sodium iodide/sodium sulphite solution due to the extremely low concentrations of each chemical.
Physical hazards
There are no known physical hazards associated with this material
Potential health effects
Inhalation: Not applicable. Skin Contact: Sodium hydroxide in concentrations ≥ 0.5 % and ≤ 2.0 % are classified as irritant. Sodium iodide and sodium sulphite in their pure forms are classified as irritants. The low concentrations in this solution are not expected to pose an irritation hazard. Eye Contact: Sodium hydroxide in concentrations between 0.5 and 2.0 % are classified as an irritant. Sodium iodide and sodium sulphite in their pure forms are classified as irritants. The low concentrations in this solution are not expected to pose an irritation hazard. Ingestion: Ingestion of this material is unlikely under normal conditions of use. If ingested seek immediate medical attention. Listed as a Carcinogen/ Potential Carcinogen: Component: Water/sodium hydroxide/sodium iodide/sodium sulphite solution Yes No In the National Toxicology Program (NTP) Report on Carcinogens X In the International Agency for Research on Cancer (IARC) Monographs X
