These bags are specially designed to protect a dosimeter from moisture and contamination when working in a nuclear power plant or other hazardous area. 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 tabs on the bag make it convenient to attach to coveralls and other protective clothing. Fold or whirl the bag over to close and then twist the ends of the tab together to secure it in place. The strong polyethylene won′t break and is SEG incinerable. These smaller size bags are designed to hold the new, smaller dosimeters.
