An arriving air passenger from Japan passes through a scanner to check radiation level at Incheon International Airport on Thursday.
As Japan struggles with the crisis at the Fukushima Daiichi nuclear power complex, fear that radiation leakage will spread across the region is rising in South Korea as well as China and elsewhere. Here, authorities have tried to keep the worries from getting out of hand.

来自主题: Automobile版 - 周末终于把坏的radiator换掉了
旧的靠近盖子塑料的部分裂了,图片radiator正面有一片白色的地方就是裂的位置。
拖了两个星期,直到老婆说再不修好不许我上床,上个周末花了2-3小时换了个新的。
今天总结一下,给大家一个参考。
两星期前开车时看到引擎盖下面冒出来一阵白烟,心里想玩了,radiator挂了,赶紧看
看水温表,已经很高了,再开了100米看到有个停车场,赶紧停下,这时水温表指针已经
到最顶了。打开盖子一看,只见radiator上面裂了有一道20厘米左右的口子,这下完蛋
了,离家还有30迈,怎么才能把车开回去呢。
坐车里等着车凉下来,脑子也不像刚才那么发热了,要想个法子把车先开回去,罐满水
是没用的,一会就会漏光了,我们这里车多人多,找个地方停也不容易,到时候温度爆表

IF THERE is a nuclear meltdown in Japan, will the radiation leakage reach

It will probably take years to reach Singapore and the impact should be
minimal, Dr Hooman Peimani told The New Paper in a phone interview.

来自主题: Automobile版 - radiator fan和空调的关系
2001 jeep GC, 前段时间空调不能制冷了,florida太热实在不能忍了
3周前拿到tire plus去花了500刀换了compressor
另外检查的时候说radiator fan工作不好,可能是造成compressor坏掉的原因,
更换需要再500刀。当时我看了一下,觉得radiator fan是转的,就没修,
只交了修compressor的钱就回来了
这周空调又不能制冷了,先到一家local的修车店检查了一下
查出来氟利昂漏光了,冲上氟,发现低压端正常,高压端压力过高,师傅的解释是:
1. 哪里可能有漏氟的地方,可能是上次修compressor遗留问题;
2. 高压端line或者extension部分不畅;
3. 其它问题
他可能觉得不太能搞定,就让我回tire plus再修。同时他觉得radiator fan工作正常,
给油的时候风扇速度会上去(2x)
回到tire plus,他们一口咬定非要换radiator fan才行,解释是:
radiator fan工作不正常,高压端就会压力高,氟利昂就会漏
不换的话迟早compressor还会坏掉。

俺的车是94 Acura Legend L,今年初开了1000 miles 的长途去马里兰,都挺好的.后

就时常开前盖看看,并老带着一瓶coolant, 时常加一加.有一回偶然发现,管子(upper)的
边缘往外漏,于是就给拧紧了.过了几天还是漏,又用铁丝把管子的头给箍上了,还是不行,
就去ACURA dealer那买了根管子上上了,20多刀呀,心疼.不过上的时候发现这个Radiator
和管子相连的那部分, 已经有一侧都没了,可能是以前别人换的时候给拧坏了.后来看还是

好区,公司专用大停车场放了一夜。CD deck和GPS也就罢了,Radiator居然被全部端了
。。。还在回味,晚些再补细节吧
报告警察,AAA拖车,向LD汇报,刚刚折腾完。虽然承受能力很强,损失说起来还可以接受,但还是很不爽。。。
警察倒是没有给太多信息,当时我还在震惊中,没缓过来没多聊。后来等AAA的时候想了不少,和AAA司机回家的路上,聊了不少。基本有个脉络了。
教训是,麻痹大意要不得啊。另外AAA司机说的有一点很对,不要每天把车放在同一个位置。
偷Radiator确实非常稀罕,不过细想说明这不是随即作案,已经惦记我的车有一段时间了。说起来敢于花功夫下radiator,为什么不多花些功夫下别的零部件。更值钱的多了。四个轮子通常是比较常见的目标。考虑到我的车model很少见,早也停产了。一定是看好了要搞我的radiator来的,cd deck,gps都是顺手。
公司的停车场,没有过路车。能看到我的车的,只有公司员工(应该决不至于想这个)和打扫卫生等勤杂。我的猜测,后来AAA司机也很肯定地说是这些勤杂,或者相关的人。实在不可能有别人深入停车场来。

radiator 只是散热没有制冷功能。
堵塞是很常见的事,有时脏东西进了coolant,或者water pump里面的螺旋叶片出现老
化,debris会进入radiator。
thermostat是测量radiator出水口的温度,这个跟你车上的发动机温度是有关联的,如
果coolant进入radiator后没有降温又重新再回到engine,就有可能产生overheat.

这个要是不好一下子拿出了.
那就只有:
1. 先把radiator拆下来.
2. 用一个粗的钻头把剩下的一半钻碎.
3. 冲洗radiator,一定要干净,要不朔料会融化在引擎缸头里的.那就麻烦大了.
4. 注意整个radiator系统里不能有空气.
5. 装回去后,换个新的hose fitting, 接好管子, 然后看看不漏.
6. 启动引擎,看看高温时,是不是引擎不过热.
7. 注意停止引擎后,高温时不要打开radiator的盖子...否则会被烫伤的!!!
要是要排气,一定要用一片厚的布包好盖子,再打开.
其本就可以了.
这个要是自己做的话,恐怕挺麻烦的...可能还需要些特殊的工具.

好像我的radiator漏了,本来要换来着,后来网上看到有个东西叫K-seal的,可以加在
coolant里面把leak填好
我对车子很不了解,不知道这东西管不管用,还请大侠们指教
车子的情况是01年的beetle,2月份的时候coolant少了那个报警灯响了,大概挨了一个
月才加满了coolant,不知道是不是因为这样后来漏了。结果才3个月,又报警了,打开
装coolant的那个东西的盖子一看,确实很少了,就又加了一点。去修车行还机油的时
候顺便让车房的人给看了一下,他说radiator漏了,要换,人工加part要600刀左右。
我想想很不值阿,反正我这旧车两年内肯定是要换了,如果我不换radiator等它报警了
就马上加coolant,大不了加的频繁写,也用不了600刀阿。
可是我是汽车小白,不知道这样做会不会有问题。
如果那个k-seal管用是不是就不用换radiator了?

要撑过这一周很简单,去pepboys或者autozone买你车用的那种coolant,50/50配好的
,放在后备箱,每天出门前冷车的时候,检查一下coolant,不够就加一些,然后凑合
着开到单位。下班回家前检查一下coolant,不够就加一些,凑合着开回家,如此反复
直到去修车。
如果在路上漏光了coolant,温度上升的厉害,要马上停车熄火把hood架起来让冷风飕

后再继续开,发现温度上升的厉害了再停下来,估计平时20分钟的路要开1个小时,但

还有就是你每天开车前最好趴到车底看看地上有没有一滩coolant,有的时候只有开车

然也有可能是radiator本身漏了(锈蚀);
3. water pump或者clutch(不是transmission的clutch)坏了。
仔细找一下看水/冷却液到底是从哪儿流出来的,基本上就能确定是哪儿的问题。
修起来都不能,零件也不贵(几十刀),但是比较费事(特别是galant这种小车,空间
太小)。

忽悠.
drain & refill? where?
if for radiator. the coolant in coolant reverve won't drain out.
从下面放水的时候难道不是整个cooling system都应该放光?
no.
to let the old coolant totally out of coolant system.
you have to take out the thermostat from the engine.
otherwise, some coolant still in engine.
disconnect two major hoses.(from radiator to engine and from engine to
radiator)

来自主题: Automobile版 - 有人用过radiator stop leak没有?
昨天发现radiator有渗漏,coolant从橡胶和金属的接缝处往外渗。
网上查了一下,换radiator还挺花钱的。
还查到有radiator stop leak,几块钱的样子。有人用过这个东西没有?顶用不?会不
会把其他什么地方搞坏,比如水泵什么的?

来自主题: Automobile版 - radiator出问题了,寻求大家的帮助
1999的toyota camry。 开一会儿就会闻到一股糊味。
今天打开让它空转了一会儿,发现radiator最上边的那个管子非常热。就是网状结构最
上边的那个连接coolant的条形管子。coolant看起来还是满的。停机后打开上边的那个
盖子,coolant冒着热气就从上边喷出来了,空转的那一会儿没看到风扇转动,
radiator下边的网状结构感觉一点都不热,只是上边的那个管子。
两年前换的新radiator。
大家帮忙诊断一下。该怎么修?

google了一下,radiator cap类似于高压锅的阀门。radiator里面液体受热产生的压力
用于推动液体循环,但压力过大时,cap用于放气。发现radiator本身和管子没有明显
泄露,就是cap四周有些喷出来的水剂,小点点。

来自主题: Automobile版 - 引擎过热,要换掉整个radiator吗

If radiator has a crack, the coolant should be leaked out fairly quickly.
Why there was no coolant low warning? You should see puddle of coolant under
the radiator when you parked your car.
Replacing a radiator should not be too hard, probably a DIY project for most
weekend mechanics.

来自主题: Living版 - 推荐radiation detector
周围的人担心日本泄漏对美国西海岸的影响。
我想自己每一个radiation detector。
我对radiation 完全是门外汉。
这个测量 的基本原理是什么呢?
比如说我想测水的radiation, 这个东西可以吗?

来自主题: Medicine版 - Radiation from CT到底有多少?
闺女14个月了,昨天晚上摔倒头撞到桌角流了很多血,所以冲去了ER 。 医生说伤口周
围有点肿建议做个CT, 爹娘两个傻人很panic就同意了(做之前问了医生关于radiation
, 医生说没什么问题…)。
回家后上网一查,铺天盖地的文章讨论high correlation of cancer and expose to
the radiation from CT, 而且似乎小朋友risk 最大。现在非常担心,因为闺女出生时
由于一些complication 已经做过一次头部CT, 两次加起来的剂量会不会有问题。所以
想问问版上Radiologists 或者是懂这方面的医生,通常这种婴幼儿头部CT radiation
dose 是多少?网上有人说 about 10 millisievert(mSv), 有人说更多。有什么方式
可以从医院查到具体的record吗?

The level around the plant's administration building rose to 4,000

TSA Admits Bungling of Airport Body-Scanner Radiation Tests
The TSA, which has deployed at least 500 body scanners to at least 78
airports, said Tuesday the machines meet all safety standards and would
remain in operation despite a “calculation error” in safety studies. The "
flawed" results showed radiation levels 10 times higher than expected.
