Abstract |

内容記述 |
It is well known that the electromagnetic fields emitted by cellular telephones can affect medical electronic devices, such as pacemakers. Therefore, it is recommended that cellular telephones with lower electronic field strengths be used in Japanese hospitals (hospital cellphones) The electronic pocket dosimeter (EPD) is a device that is used for real-time monitoring of radiation exposure from radiation sources such as radioisotopes and X-ray tubes. Recently, with the increased use of positron emission tomography (PET) examination, EPDs have become more important for radiation monitoring in nuclear laboratories, especially PET laboratories. Although there have been some reports that the electromagnetic fields emitted by cellular telephones (conventional cellphones) can cause abnormally high EPD values, it is not clear whether the electromagnetic fields emitted by hospital cellphones affect EPDs. Therefore, we investigated the effects on EPDs of the electromagnetic fields emitted by hospital cellphones. Two types of EPD (with more or less shielding against electromagnetic fields: high-shield and low-shield EPDs, respectively) were exposed to the fields emitted by two types of cellular telephone for 20 seconds (conventional cellphone vs. hospital cellphone). With the high-shield EPD, neither the conventional cellphone nor the hospital cellphone had any effect. With the low-shield EPD, the distance that prevented electromagnetic interference (protection distance) was identical for both types of cellphone (2.5±0.58vs.2.75±1,5cm,p=0.766). As regards the relative positions of the EPDs and cellphones, there was no significant difference in the protection distance between side-by-side and overlapping (p=0.100), although the distance tended to be greater in the overlapping position (2.0±0.82vs. 3.25±0.96 cm,p=0.100). The maximum dosage error for the low-shield EPD tended to be lower for hospital cellphones than for conventional cellphones (1,789±1,547vs. 3,868±1.321μSv), but the difference was not statistically significant (p=0.111). Although the electronic field emitted by hospital cellphones is weaker than that emitted by conventional cellphones, we found that both types produced abnormally high readings with low-shield EPDs. Therefore, we recommend the use of high-shield EPDs. |
