回答(1):

μSv/h是微西弗每小时,Sv/h是西弗每小时。1Sv/h=1000000μSv/h

微西弗又叫微希沃特,是放射性剂量的计算单位之一,放射性剂量的标准单位叫做西弗,定义是每千克人体组织吸收1焦耳能量(放射过程中释放的能量)为1西弗。

西弗是个非常大的单位,因此通常使用毫西弗、微西弗。1西弗=1000毫西弗;1毫西弗=1000微西弗。对日常工作中不接触辐射性工作的人来说,每年正常的天然辐射(主要是因为空气中的氡辐射)为1000~2000微西弗。

一次小于100微西弗的辐射,对人体无影响。与放射相关的工人,一年最高辐射量为50000微西弗。一次性遭受4000毫西弗会致死。就拿中国的标准来讲,每一个人都受到一定天然本体放射性的照射,也就是说在中国这个领土情况下,地质情况下,每个人每年所受到的积累量是2.7个毫西弗,等于2700微西弗。

扩展资料

放射性检测单位概念:

在苏联“切尔诺贝利”核事故时,采用单位为“伦琴”,“伦琴”等于10“毫西弗”。即:1西弗=1000毫西弗;1毫西弗=0.1伦琴=1000微西弗。

在放射医学和人体辐射防护中,辐射剂量的单位有多种衡量模式和计量单位。较为完整的衡量模式是“当量剂量”,是反映各种射线或粒子被吸收后引起的生物效应强弱的辐射量。其国际标准单位是“西弗”,定义是每千克人体组织吸收1焦耳为1西弗。

防辐射办法:

1、进入空气被放射性物质污染严重的地区时,要对五官严防死守。例如,用手帕、毛巾、布料等捂住口鼻,减少放射性物质的吸入。

2、穿戴帽子、头巾、眼镜、雨衣、手套和靴子等,有助于减少体表放射性污染。

3、要特别注意,不要食用受到污染的水、食品等。

4、如果事故严重,需要居民撤离污染区,应听从有关部门的命令,有组织、有秩序地撤离到安全地点。撤离出污染区的人员,应将受污染的衣服、鞋、帽等脱下存放,进行监测和处理。

5、受到或可疑受到放射性污染的人员应清除污染,最好的方法是洗淋浴。

回答(2):

μSv/h是微西弗每小时,Sv/h是西弗每小时。1Sv/h=1000000μSv/h
【补充】:
毫西弗是辐射剂量的基本单位之一。辐射剂量的主单位是西弗(sv),但西弗是个非常大的单位,因此通常使用毫西弗(mSv),1mSv=0.001Sv。此外还有微西弗(μSv),1μSv=0.001mSv。对一般人来说,比如在日常工作中不接触辐射性物质的人,每年的正常因环境本底辐射(主要是空气中的氡)摄取量是每年1~2毫西弗。

DECREE OF THE STATE COUNCIL CONCERNING THE USE OF UNIFORM LEGAL
MEASURES IN THE COUNTRY
(Issued on February 27, 1984)
Since the State Council issued the Decree Concerning the Unification of
the System of Measurement in 1959, which stipulates that the metric system
is the basic system of measurement in the country, remarkable achievements
have been made in promoting the metric system, reforming the Chinese
market system, restricting the British system and abolishing the old and
mixed systems in China. In order to implement the policy of opening up to
the outside world and invigorating the economy at home, meet the needs of
developing the national economy and cultural and educational undertakings,
promote the advancement of science and technology and broaden
international economic and cultural exchanges, the State Council has
decided to further unify the measures of the country on the basis of
adopting the advanced international system of measurement. The 21st
Executive Meeting of the State Council held on January 20, 1984 discussed
and approved the following documents submitted by the State Measurement
Bureau: the Report Concerning the Use of Uniform Legal Measures in the
Country, the Suggestion Concerning the full Application of the Country's
Legal Measures, and the Legal Measures of the People's Republic of China.
The Decree is hereby issued:

I. The Legal Measures of the People's Republic of China (see the Appendix)
shall be adopted in any measurement in our country.
II. The Chinese market system of measures currently in use in daily
commercial activities may remain applicable till the end of 1990, before
which the transition to the national legal measures must be completed. As
for the reform of farmland measures, a reform plan shall be drawn up and
promulgated separately on the basis of investigation and study.
III. The reform of measures is a matter which concerns all walks of life
and broad masses of people. Leading cadres in the various localities and
departments must pay adequate attention to it and formulate vigorous and
reliable plans of implementation so as to ensure its successful
completion.
IV. The State Measurement Bureau shall be vested by this Decree with the
responsibility of the implementation thereof.
This Decree shall go into effect from the date of issuance. If any
previous provisions come into conflict with this Decree, this Decree shall
prevail.
THE LEGAL MEASURES OF THE PEOPLE'S REPUBLIC OF CHINA
The legal measures of the country (hereinafter referred to as the legal
measures) include:
(1) basic units of the international system of measurement (see Table 1);
(2) auxiliary units to the international system of measurement (see Table
2);
(3) units derived from the ones with special names in the international
system of measurement (see Table 3);
(4) units of non-international system of measurement chosen by the State
(see Table 4);
(5) units formed by combining the above units;
(6) units formed by the symbols (see Table 5) and the above units
multiplied or divided by 10.
The definitions, uses, etc. of the legal measures shall be stipulated
separately by the State Measurement Bureau.
