JNSA reprimanded TEPCO for not having a monitor for every worker, and some workers had to share monitors.
Actually, this is the practice in the United States - one guy (a Health Physics, or HP, technician) surveys the area first...then the rest of the team enters the work area after the risks have been assessed.
Monitors are not dosimetry. Monitors measure the rate of activity in an area. You multiply the rate by the time you will spend in the area to estimate the dose you will receive. Dosimetry measures the actual total amount of dose that one person receives.
If I’m working next to a guy who has a monitor (your article said some teams had to share), I’m going to experience the same dose rate that the rest of the team is, and I’ll know whether or not I’m getting into a hot spot or not.
Look, if you hear a report of a Japanese radworker reaching or exceeding his limit, let me know. Then we’ll discuss whether or not his cancer risk has increased by more than 2%. Radworkers without dosimetry in low dose rate areas and radworkers having to share monitors doesn’t even qualify as health risk; rather it is a violation of Japanese regulations.
