Answer:
Hair
Explanation:
The scientist predict that the contamination occurred several months ago. Under normal circumstances, most organisms would no longer have a trace of exposure in their urine or blood after 3 months. If the organisms exposed to the radioactive three months ago and do not come near that area again within 3 months, the scientist wouldn't be able to identify it.
But, if that substance got into their hair, it will last way longer than that. Hair Analysis is very common to be used among forensic toxicologist to identify contamination that occurred months because of this.
To test the theory, hair from mammals living in the habitat should be collected and analyzed for radioactive.
What should be isolated in order to test?
The contamination, according to the scientists, occurred several months ago. Most organisms would have no sign of exposure in their blood or urine after 3 months under typical circumstances.
The scientist would not be able to identify it if the organisms were exposed to the radioactive three months ago and did not get near that location again within three months.
However, if the chemical gets into their hair, it will linger much longer. Hair analysis is commonly used by forensic toxicologists to discover the contamination that has been present for months.
Therefore, to test the hypothesis, the radioactivity of the following substances might be examined, human hair created in the environment.
