How is radioactive material identified?
A RIID is a radiation detector with the ability to analyze the energy spectrum of radiation, in order to identify the specific radioactive material (radionuclide) that is emitting the radiation. In addition, these devices can be used as survey instruments to locate radioactive material.
How do you calculate the transport index of a radioactive material?
The transport index is the number determined by multiplying the maximum radiation level in millisievert (mSv) per hour at 1 meter (3.3 ft) from the external surface of the package by 100 (equivalent to the maximum radiation level in millirem per hour at 1 meter (3.3 ft)).
What packaging technique is used to package damaged radioactive materials and contaminated sources?
Industrial Packaging
Industrial Packaging is used in certain shipments of low activity material and contaminated objects, which are usually categorized as radioactive waste. Most low-level radioactive waste is shipped in these packages.
How do you measure radiation levels?
By measuring the radiation level around a person’s body using a Geiger counter, a safety officer can approximate that person’s absorbed dose. A more sophisticated measure of radiation exposure, called the effective dose, accounts for the harmfulness of the specific type of radiation present.
How is radiation device measured?
A Geiger counter (also known as Geiger–Müller counter or Geiger–Muller counter) is an instrument used for detecting and measuring ionizing radiation….Geiger counter.

What is the transport Index a measure of?
Transport index (TI) means the dimensionless number (rounded up to the next tenth) placed on the label of a package, to designate the degree of control to be exercised by the carrier during transportation.
What does a transport index of 3.5 mean?
certificate of competent authority. current leak test. What does a TI of 3.5 mean? The highest dose rate 1 meter from the source shield is 3.5mRem/hr.
How much does a radioactive material package weigh?
UN ID 2916: (Radioactive material, Type B (U) package [non fissile or fissile-excepted) Caution: RADIOACTIVE SHIELDING, DEPELETED URANIUM 34 lb15 kg, TOTAL WEIGHT 52.91lb. 24 kg The following documents provide more details about package types with videos, and pictures Radioactive Material Shipping Packages (YouTube – 5:48) (DOE/TEPP/MERRTT)
How do you ship radioactive materials?
If the amount of radioactivity you’re trying to ship is less than the A1 activity (for special form radioactive material) or less than the A2 activity (for normal form) then you can ship the radioactive material in a Type A container. If you’ve got more than that then you have to use a Type B container. OK – so how does this work in practice?
What is normal form radioactive material?
Normal form (also called “other than special form”) is everything else. These are unsealed radioactive materials – it could be contaminated soil from a remediation project, radiopharmaceuticals intended to be injected into patients to diagnose disease, or radio-labeled chemicals intended for use in research.
What does RQ mean on a radioactive substance?
The “7” indicates this is a Class 7 hazardous substance, where Class 7 indicates radioactive material. “UN 3332” is the United Nations hazardous material designation (UN number) for non-fissile special form radioactive material. “RQ” indicates this package contains a “Reportable Quantity” of radioactive material (see above).
