Information Request

Requesting information

I am updating information used in our training of radiation workers in
general laboratory environments. Being a one-person show, I lack the time to
explore all the needed information. I thought that I would turn to you for
assistance.

Our training material includes a list of commonly used radioisotopes.
Table-1 below is what we provide as a handout. I would like to explore if
more radioisotopes are commonly used for this audience. Table-2 is the
information that we provide about each radioisotope listed (if possible). 

Please add other radioisotopes you feel are commonly used. Also, would you
please select a couple of the radioisotopes and complete the information
about the radioisotope(s). I will compile the information and make it
available to who ever would like a copy. If you feel the information list
should be expanded, what information do you recommend? Please remember the
audience. 

The information will be included in a text. If possible identify the
references. I know that this is a great deal to ask. You can see I will be
unable to obtain all of the information myself. 

Many thanks,

John Pickering

Table-1

H-3, C-14, Na-22, P-32-, P-33, S-35, Cl-36, Ca-45, Cr-51, Fe-55, Co-57,
Fe-59, Co-60, Cs-137, I-125, I-131. 

Table-2

Maximum energy (keV or MeV)
Maximum range in air (feet and/or meters)
IAEA radiotoxicity classification
Typical dose rates expected (3 mrad/hr at 1 cm, etc.)
Physical half-life
Biological half-life (preferably in days)
Critical organ (whole body, thyroid, etc.)
Personnel monitoring (urine analysis, blood, etc.)
Annual Limit of Intake (most common method(s) expected)
Shielding requirements (lead, plastic, if any, etc.)
Special considerations (Volatile, wear two pairs of gloves, produces x-rays,
avoid skin exposure, use thin-end window G-M or solid scintillation
detectors, use safety glasses, special problems when handling halogenated
acids, etc)
