The Attempt at a Solution
i believe that a half-life of several years is too long to gather the data
but i can't figure which of the 2 emitter and why?
the answer is given to be C
i've taken a look at the characteristic of both, but can't figure which one of them to use here.You're given two different decay mechanisms/modes from which to choose. What are the characteristics of the two?
Step 1: read the question. Step 2: when step 1 fails, re-read the question. Step 3: repeat step 2 until you are familiar with the information given in the question.it was
notsaid in the question. should this be known?
i don't understand. the answer is gamma rays. if the water can't be drunk, it should not be the emitter?
I read again, but it's really not said in the question?Step 1: read the question. Step 2: when step 1 fails, re-read the question. Step 3: repeat step 2 until you are familiar with the information given in the question.
so, it is detected through a pipe. but how does the 2 differ?You included it with the problem statement in the template; "In order to trace the line of a water pipe buried 0.4 m beneath the surface of a field ...."
basically they are all radiations, with different properties and characteristics.Have "alpha, beta, and gamma" decays been defined/explained to you at all?
