Can I use SIRAD instead of TLD, film and quartz fiber dosimeters?
A. The answer is clearly No. Those who use these and similar low dose dosimeters must continue using them. SIRAD is not a substitute for any low dose dosimeters. SIRAD is a high dose (higher than about five rads) dosimeter. It can be used along with dosimeters such as TLD and film in order to instantly know exposure to high dose.
