Americium 241 is used to measure: Moisture Content. Which is the least penetrating type of radiation? Alpha. When shipping by air, nuclear gauges can only be shipped on cargo aircraft. T. A TLD or film badge is worn to: To measure radiation exposure.

It is used worldwide to measure the rate of production by oil wells. The predominant commercial use is in ionization-type smoke detectors. /Americium-241/ The gamma rays from americium-241 are used in portable X-ray machines that can, for example, be taken into oil fields to help determine where new wells should be dug. Americium-241 is also used to measure the thickness of materials. For instance, a small piece of americium-241 can be placed above a conveyor belt carrying newly made glass. Smoke detectors are common household items that keep you and your family safe by alerting you to smoke in your home.
