The Whirl-PakŪ Dosimeter Bag is designed specially for nuclear power plants and will protect your dosimeter while working in a contaminated area. Simply insert the dosimeter into the bag upside down, whirl the bag completely over or fold the top down, then use the extra long tabs to secure the bag to clothing by twisting the ends together. Just lift the bag up to read the dosimeter. Strong polyethylene won't break and is SEG incinerable. The clear bag is easy to see through and features large red stripes to make the bag highly visible.
