Final answer:
The threshold for when an area should be decontaminated after a wipe test is not specified in the question; it varies based on laboratory standards. The term 'thermal death time' refers to the time needed to kill all microbes in a sample at a certain temperature.
Step-by-step explanation:
An area wipe test of 100 cm2 that exceeds a certain number of disintegrations per minute (dpm) should be decontaminated, re-wiped, and results recorded. While the exact threshold value can vary depending on regulatory standards and the specifics of the laboratory or facility conducting the test, the answer you are looking for in a multiple-choice format may be provided by your instructor or governing safety protocols.
In regard to the reference information provided, the term used to describe the time required to kill all of the microbes within a sample at a given temperature is C. thermal death time. This is an important concept in microbiology, particularly in the context of sterilization and disinfection processes.
