Comment That's not a Geiger Counter (Score 1) 160
The item shown in these pictures is not a Geiger Counter. It is a Victoreen. The difference being that a Geiger Counter measures the number of decay incidents in a given period of time, whereas a Victoreen measures the amount of radiation exposure in a given period of time.
The difference being that, while a Geiger Counter may be a useful tool for knowing that there are radioactive emissions are occuring (and at what rate), it is not nearly as useful as a Victoreen for quantifying what type of dosage one is receiving and what the effects might be on the human body.
