在一些特殊的工作場合,射線對(duì)工作人員的造成的嚴(yán)重的危害,為了保護(hù)工作人員們的健康,我們需要一些射線防護(hù)器材!
In some special working occasions, radiation causes serious harm to workers. In order to protect the health of workers, we need some radiation protection equipment!
人體組織結(jié)構(gòu)的密度可歸納為三類:屬于高密度的有骨組織和鈣化灶等;中等密度的有軟骨、肌肉等;低密度的有脂肪組織以及存在于呼吸道、胃腸道、鼻竇和乳突內(nèi)的氣體等.
The density of human tissue structure can be classified into three categories: high density bone tissue and calcification focus; medium density cartilage and muscle; low density adipose tissue and gas in respiratory tract, gastrointestinal tract, nasal sinus and mastoid process.
人體組織結(jié)構(gòu)和器官形態(tài)不同,厚度也不一致.其厚與薄的部分,或分界明確,或逐漸移行.厚的部分,吸收X線多,透過的X線少,薄的部分則相反.人體各部位細(xì)胞對(duì)X射的反應(yīng)程度不一,其中以性腺為敏感.輻射能夠引起生殖細(xì)胞遺傳物質(zhì)的變化,形成遺傳效應(yīng).這種變化表現(xiàn)為基因突變和染色體畸變.近年來,對(duì)輻射的遺傳效應(yīng)有了一些新的認(rèn)識(shí),認(rèn)為在小劑量范圍內(nèi)對(duì)遺傳方面的影響不大.

The thicknesses and thicknesses of the tissues and organs of the human body are different. The thicknesses and thinnesses of the tissues or organs are clearly demarcated or gradually migrated. Thicknesses absorb more X-rays and transmit less X-rays, while thinner ones are opposite. Cells in different parts of the human body respond differently to X-rays, of which gonads are the most sensitive. Radiation can cause genetic material in germ cells. In recent years, there has been some new understanding of the hereditary effects of radiation, and it is believed that the effect on heredity in a small dose range is not significant.
但是我們熱然不能掉以輕心,選購一臺(tái)射線防護(hù)器材,更讓人安心!
But we can't take it lightly. It's more reassuring to buy a radiation protective equipment.
