Fold the bag over two to three times to close, and twist the ends of the tab together to secure it in place.The bold, red stripes make the bag highly visible so it will be seen quickly if it falls into the cooling water.The dosimeter can be read easily through the clear polyethylene, so there is no need to remove it.The extra long wire tabs on the bag make it convenient to attach to coveralls and other clothing.The strong polyethylene won’t break and is SEG (Scientific Ecology Group) incinerable.
