which radiation detection device is the best to use for measuring the presence of radiation in large moving objects where constant monitoring is impossible?\nfilm badge\ngeiger counter\ncloud chamber\nscintillation counter
Answer
Brief Explanations:
A Geiger - counter is portable and can quickly detect radiation. Film badges are for long - term exposure monitoring, cloud chambers show the path of radiation particles rather than quick detection for moving objects, and scintillation counters may be more complex and less suitable for quick checks on moving objects.
Answer:
B. Geiger counter
