Due to housing a certain amount of waste package in waste temporary library, in addition waste temporary library and compression packaging operation between adjacent, work
Make personnel when carrying out compression packing related work, it can be by a degree of radiation exposure.Simultaneously as Environmental dose rate
It increases, measuring operation to pail for used dressings surface contact agent dose rate also brings along certain interference, causes measured value error larger.
To reduce personnel's radioactive dose, the accuracy of pail for used dressings Dose rate measurement is improved, need to be had to waste temporary library
The shielding of effect.At unit operation initial stage, the measure of use is that suspension lead shield, such method have at waste temporary library channel
Certain shield effectiveness.But since the thickness of lead shield is smaller, if wanting radiation level being down to desirable level, it is necessary to hang polylith
The mass density of lead shield, lead is larger, is shielded by the way of hanging lead shield, and there are larger to fall risk, to waste goods
Packet conveying track causes a degree of damage and personnel may be caused to injure.In addition, personnel to waste vault carry out inspection or
When cleaning, since simple and crude, personnel's disengaging waste vault inconvenience is built in lead screen, meanwhile, also influence the tidiness in room.
It is bad and there are problems that security risk for the shield effectiveness of suspension lead shield, in conjunction with live practical, shield from being promoted
Cover effect, the possibility for avoiding lead shield from falling and personnel by convenience start with, will shielding and door function integration, if
Meter has made shield door, reduces the radiation level of workplace, reduces staff's radioactive dose, it is temporary to improve waste
The safety of warehousing shielding and convenience.
