Abstract
The background of this work was an increase in interventional and diagnostic
procedures with ionizing radiation, which in their complexity require prolonged wearing
of radiation protection systems and are associated with an increased risk for the
occurrence of orthopedic diseases, especially of the spine. Therefore, in this study work,
the weight force load exerted by a free-hanging radiation protection system on the
shoulders of subjects was measured. The aim of the study was to compare these
measurements, during standardized fixed movement sequences, with those of
conventional radiation protection devices, such as classic lead protective aprons. The
aim was to investigate whether a free-hanging radiation protection system can
significantly reduce the weight load on the operating personnel and thus possibly reduce
the risk of the occurrence of orthopedic complaints.
The free-hanging Zero-Gravity system from Biotronik was used. The measurement
results were compared with the most common radiation protection aprons. Specifically,
a radiation apron - one-piece - open and closed at the back, each with an open and
closed belt, and a radiation apron - two-piece - consisting of a radiation protective vest
and skirt. A sample of (n=) 17 subjects was evaluated. Study participants performed a
fixed sequence of movement patterns, adapted from interventional radiology
movements, while wearing the different radiation protection systems. The weight force
load was measured on each of the two shoulders with a 3-D force sensor.
In an overall comparison to all other systems, the Zero-Gravity System achieved
significant weight force reductions in each case. The highest reduction (85.5%) was
measured in comparison with the one-piece without belt and the lowest reduction
(74.3%) with the two-piece. When the one-piece was worn with a belt, the weight load
on the shoulders was reduced by 30.7% compared to the one-piece without a belt.
By inserting different conventional radiation protective aprons, a weight load reduction
on the shoulders can also be achieved, but less significantly than in comparison with the
zero-gravity system. The weight load on the shoulders was measured and it was not
investigated where the weight is alternatively distributed.

The Zero-Gravity System and the one-piece simply showed no significant differences in
the shoulder comparison. For the two-piece, the weight load on the left shoulder was
higher than on the right shoulder, and for the one-piece with and without a belt, the
load on the right shoulder was higher than on the left shoulder. The difference in
shoulder loading may be related to the different closure systems of the aprons.
During the different movement sequences, there was mostly a reduction of weight on
the shoulders in the comparison "standing" to "arm movement" and "bending forward".
When comparing "stand" to "forward/backward", "sideways" and "upper body
rotation", there was an increase in weight load for almost all systems. This is probably
related to the different weight distribution that occurs with different movements. It is
possible that orthopedic problems may arise as a result of the ergonomics at the
workplace and the way the body is positioned when wearing personal radiation
protection equipment. Further studies should be initiated to investigate the exact
relationship between increased weight load, due to wearing personal radiation
protection at the workplace, and orthopedic complaints.
In summary, it can be said that physical strain can be significantly reduced by the use of
a free-hanging radiation protection system, compared to classic radiation protection
aprons. It is possible that the motion sequence and differential loading of the shoulders,
coupled with high weight bearing, have a greater impact on the development of
orthopedic disease than previously thought. More research is needed in the future to
investigate these relationships.
