Random Sampling
Instantaneous sampling is one method used for sampling a continuous time signal into discrete time signal. This method is called as ideal or impulse sampling. In this method, we multiply a impulse function with the continuous time signal to be sampled. The output is instantaneously sampled signal.

This type of sampling method is used when data is gathered by sampling individuals from a certain group. For example, a researcher may ask for a sample of 200 students from an ivy league school as a sample for their survey.
Sampling is a method of selecting experimental units from a population so that we can make decision about the population. Sampling design is a design, or a working plan, that specifies the population frame,sample size, sample selection, and estimation method in detail. Objective of the sampling design is to know the characteristic of the population.

No, the common method of measuring radioactivity at job sites is typically done using a Geiger-Muller counter or a scintillation detector. These devices are more accurate and sensitive in measuring radioactivity levels compared to an electroscope.
Random Sampling
You are correct; convenience sampling is not random sampling.
Answer is Quota sampling. Its one of the method of non-probability sampling.
because it is the simplest sampling technique which requires less time and cost.
