Japanese food producer Meiji announced to recall about 400,000 cans of infant formula after traces of radioactive cesium were found in the company's milk powder. After test the products of formula on October 2012 expiration date detected cesium-134 and cesium-137 at levels 15.2 becquerels per kilograms and 16.5 bq/kg. This number actually still below the government's permissible levels of dairy for infants about 200 bq/kg. But growing child up to 9 months still sensitive to the effects of radiation, and have been focus of health concern since March 11's triptych of disaster sent radioactive plumes across Japan's airspace.
For years, Japanese food exports have been lauded for their safety and quality in Asia and beyond; after thousands of children were sickened by melamine tainted formula in China in 2008, trusted Japanese brands of milk powder flew off Asia's shelves. Since March traces of radioactive materials have been found in several Japanese products grown or processed in the vicinity of the crippled Fukusima Dai ichi power plant, from fish and beef to rice, vegetable and tea.

Drilling Method
To find oil source from the earth or Exploration is done by geologist. Modern technology to find oil is used by satellite imagery and stone surface analyze. After geologist doing a series of analyses and determine on that location contain of petroleum, the next task take over by geophysics.
Geophysicists study the characteristic of soil layer. Several method is done on this step to support the result of geologist. Many measurement equipment use to find oil, Gravimeter to measure if there is oil flow because of little different of gravitation, Magnetometer to measure the changes of magnetic because of oil flow, and sniffers the electronic measurement to detect hydrocarbon, but the often use seismology.
The work of seismology to find oil:
Seismology can use to find the oil resource in the land or under the sea. The main part of seismology is vibration trigger and signal receiver. Vibration trigger use such compressed air gun especially use offshore exploration, Thumper truck for land exploration and explosive material.
