,Threshold Limit Value-Ceiling (TLV-C) - ✔✔ANSW✔✔..Maximum concentration to
which healthy adult can be exposed w/o risk of injury
Comparable to IDLH
Threshold Limit Value- Short Term Exposure Limit (TLC-STEL) - ✔✔ANSW✔✔..Max
concentration averaged over 8 hours to which a healthy adult can be repeatedly
exposed for 8 hr/day, 40 hr/wk
Radiation Absorbed Dose (rad) - ✔✔ANSW✔✔..Used to measure a quantity called
absorbed dose
Roentgen (R)
(Ran-kin) - ✔✔ANSW✔✔..Unit of exposure to ionizing radiation
Roentgen Equivalent Man (REM), Millirem (mrem), and Microrem (μrem) -
✔✔ANSW✔✔..Rem is a large amount of radiation, so the mrem, which is one
thousandth of a rem is often the dosage encountered
Sievert (Sv), Millisevert (mSv), Microsievert (μSv) - ✔✔ANSW✔✔..Sievert is unit of
radiation absorbent. mSv is one thousandth of an Sv, & the μSv is one millionth of an Sv
Time: Shorter time of exposure, lower dosage received
Distance: Further from the source, less exposure
Shielding: PPE can only protect against alpha particles. Shielding materials include,
Lead, cement, and even water
Exposure Routes - ✔✔ANSW✔✔..Absorption: Absorbed into body through skin or other
external tissues
Ingestion: Process of consuming contaminated food or water
Inhalation: Toxins enter body through the lungs
Injection: Toxic substance introduced directly into the blood by a needle, cannula, or
some other mechanical means
Target Organ Effects - ✔✔ANSW✔✔..Reference Table 1.3, Pg 1-119
Dose Response - ✔✔ANSW✔✔..Refers to manner in which the body reacts to toxic
substance exposure. Response will depend on the concentration of exposure at the
site, material itself, and the dose administered
, Synergistic Effects - ✔✔ANSW✔✔..Results from the interaction of more than one
product
Response Objectives - ✔✔ANSW✔✔..1. Rescue
2. Public Protective Actions
3. Spill Control, Leak Control, Fire Control
