    Abstract: Organic food is welcomed by the general public because people think organic food is more environment-friendly and can introduce a healthy lifestyle. This popular notion is under scrutiny recently. Compared with conventional food, does the organic food we obtained from local farms and/or supermarket chains are actually chemically healthier? In this ... Show More

    Abstract: Personal dosimetry is the means of monitoring workers under ionizing radiation in Madagascar. This dosimetry consists in measuring the operational quantities Hp (10) or Hp (0.07) (equivalent doses to the whole organism and to the skin) and to check that these values do not exceed the authorized annual dose limit. In fact, dose limitation is one of ... Show More

    Abstract: Background: In diagnostic radiology, focus on patient’s dose measurement has been on the estimation of entrance skin surface dose and its equivalent risk assessor (effective and organ doses). So, this study identified DAP’s as capable of performing same function as ESD in patient dose monitoring. Thus, reported estimates on dose area product (DAP) ... Show More
