Nuclear Gauge Safety Certification Course Acute radiation exposures are best described as: Large doses over a short period of time Radioactive decay is: Radiation The hazard class for the gauge is: 7 When transporting a gauge you can safely secure, block and brace it in the front seat. False If you arrive back at the office and the gauge is missing from the back of the pick -up truck you should: Immediately contact the RSO and regulatory agency Elements that have the same number of protons and neutr ons are considered: Stable How many Yellow II Radioactive Labels must be affixed to the gauge case: Two The time it takes for a radioactive material to decay to ½ its activity/strength is known as a half -death. False 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. True A TLD or film badge is worn to: To measure radiation exposure Because of ionization nuclear radiat ion exposure can be harmful to human tissue. True A gauge case with a hole worn in the base can be patched and used. False Isotope refers to: A variation of a given element Which acts as an effective shield for alpha radiation? All of the above Gauge inventories are to be taken: Every 6 months Which two documents must you have readily visible and accessible whenever you transport a gauge? Emergency response sheet and bill of lading Radioactive decay typically comes from what part of the element: Nucleus What are the two types of radioactive material used in the gauge? Cesium and Americium You can transport the gauge inside of any case provided it is blocked and braced. False Which of the following do not require HAZMAT training: Accountant Cosmic radiation is considered to be an occupational exposure. False Radiation safety training for gauge operators is required. True Radioactive Yellow II moisture density gauges must use placards. False Nuclear gauges can only be shipped on cargo aircraft. True The exposure limit for a declared pregnant worker during the pregnancy is typically: 500 millirem A general license is needed to own a moisture density gauge. False
