The authors present the result of pilot measurements of electromagnetic fields (EMF) in the surrounding of some toys available on the Polish market. The measurements were compared with safety standards set in Poland to ensure occupational safety and hygiene regarding appliances producing EMF and the environmental protection.
EMF intensity was measured in the surrounding of six walkie-talkie sets (frequencies: 49.2 MHz; 50 MHz, and 446 MHz) and 8 radio-controlled (RC) toys (frequencies: 27 MHz; 44.5MHz, and 49 MHz). Constant EMF was measured in the surrounding of 4 mechanical toys with battery powered wire and wireless steering.
Walkie-talkie type toys and remote controlled toys are the source of EMF with intensity values ranging from 1 to 21.5 V/m. EMF values over 0.01 mT were not found in the surrounding of mechanical toys.
Although EMF values in the surrounding of toys meet the requirements defined by CE labeling, several toys produce in its surrounding EMF values exceeding maximum allowable intensities according to Polish environmental regulations and corresponding with protective zones defined by hygiene norms set to protect persons working with EMF-producing devices. The magnitude of exposure caused by aforesaid toys depends on both the kind of toys and the age of children playing with them.
作者展示了对波兰市场上一些玩具周围电磁场(EMF)进行试点测量的结果。将这些测量结果与波兰制定的安全标准进行比较,以确保与产生电磁场的电器相关的职业安全与卫生以及环境保护。
在六部对讲机(频率:49.2兆赫兹、50兆赫兹和446兆赫兹)和八个无线电遥控(RC)玩具(频率:27兆赫兹、44.5兆赫兹和49兆赫兹)周围测量电磁场强度。在四个带有电池供电有线和无线操控装置的机械玩具周围测量恒定电磁场。
对讲机类玩具和遥控玩具是电磁场源,强度值在1至21.5伏/米之间。在机械玩具周围未发现超过0.01毫特斯拉的电磁场值。
尽管玩具周围的电磁场值符合CE标签规定的要求,但根据波兰环境法规,一些玩具在其周围产生的电磁场值超过了最大允许强度,并且与为保护使用产生电磁场设备的人员而设定的卫生规范所定义的保护区相对应。上述玩具造成的暴露程度取决于玩具的种类以及玩这些玩具的儿童的年龄。
