In Order To Accurately Measure Any Physical Amount, A Unit Is Often Required. The International Commission On Radiation Units And Measurement (ICRU) Is Responsible For Conducting Periodic Reviews And Updates Of The Ideas In Radiation Physics That Pertain To Quantities And Their Units. These Concepts Are Essential For The Management Of Radioactive Waste. Within The Work Area, The Radioactive Waste Needs To Be Recognized And Separated Into Several Categories. The Collection Of Solid Radioactive Waste Should Be Done With Garbage Collection Bins That Are Operated By Foot And Have A Polythene Lining That Is Disposable. For The Collection Of Liquid Waste, Polythene Carboys Should Be Used. It Is Strongly Recommended That Radioactive Waste Not Be Collected In Glassware.
