Nuclear Gauge Questions And Answers

RSO stands for - Answer-Radiation Safety Officer What is a RSO's duties - Answer-To have security and control of radioactive materials. Completeness and accuracy of all information by the regulatory agency. Knowledge about contents, license and its conditions. The need to commit adequate money and resources. Selecting an individual to serve as the RSO. What is ALARA - Answer-The philosophy to achieve occupational and public doses that are As Low As Reasonably Achievable. It minimizes exposure to radiation. There are two types of radiation in the nuclear gauge. What are they and what do they do? - AnswerCesium 137 - emits gamma ray photon radiation to determine density. Americium 241 - (Combined non-radioactive Beryllium) Emits neutron radiation to determine moisture content. What are the two rods called in the gauge? - Answer-Source rods and long rods The source rod is what comes out the bottom of the gauge that goes below the surface. The long rod is what is on top of the gauge. It has the measurements and the trigger to push the source rod below.How many levels of shielding are in are from the source of the rod - Answer-Three T/F There has never been a case where the metal encapsulation has failed or been penetrated. - AnswerTrue T/F Gauges have contaminated and affected the operator. - Answer-False T/F A gauge can explode - Answer-False. It can't. No matter what. T/F The radioactive source can make us radioactive - Answer-False - But it can give us cell damage. Gauge radiation is the same type of radiation used for x rays, hospitals and airports - Answer-True There are four types of radiation in the gauge. What are the other two types? - Answer-Alpha radiation decay and beta radiation decay What is the difference between alpha and radiation decay? - Answer-Alpha radiation decay- Has two protons and two neutrons. Can be easily stopped by a sheet of paper or by your skin. Beta radiation decay - Beta radiation typically consists of a very low mass electron that travels very fast. The negative charade will only penetrate matter to a short distance. Note: You will never be exposed to these types of radiation. This type of radiation has no charge and can be highly penetrating to humans but is shielded by hydrogen plastic. It also determines the moisture content. - Answer-Neutron Radiation
