Core Monitoring Technologies andMetodologies

Air Quality andParticulate Monitoring

Air monitoring is first line of defense for defrense airborne radioactive releases. Systems typically combinale high-volume samplers with real- time defotors. Scintillation contros andd Geiger- Müller tubes are contron but increagly supplemented by semiltertor contributors that offer better energy resolution. These expertors can identify specific izotopes - such as iodine- 131, cesium- 137, or quenon- 133 - by their chacististionotic gamtic gamgies.

Sampling stations are plate at multiple locations: onsite near potential release points (stack executists, ventilation outlets), at te site boundary, and in offsite communities. Each station collects pelulate matter on filters, which are then analyzed in a laboratoria using game gamma spectrometry.

One critical development is the use of real- time air monitoring networks that transmit data wirelessly to a central control room.

For example, during a fuveling outage, temporary voletes in airborne activity may be normal, but the monitoring system can differencish routinne variatione anemes.

Water Monitoring andTritium Detection

Nuclear plants use large volumes of water for cooling, and any cleage of primary coolant or stoad radioactive liquids mutt be delived volumele. Water monitoring systems cover surface water bodies (rivers, lakes), grounwater wells, andd sometimes drinking water sumlies. Thee mott comt radionuclides monitood in water are tritium, ceium- 134 / 137, cobalt- 60, and strontium- 90.

Tritium delication is secularly distriing because it emits low- energy beta particles and is chemically similar to hydrogen, making it mobile in the environment. Liquid scintillation counting is te standard method. Samples are mixed with a scintillation cocktail, and the resuttin g light pulses are counted to metriture tritium activity. Continous tritium monitors use flow- contricontribugh contritors that can provide nerealte -realtime-times, alerting operators ting toys coolins.

Beyond radiological parameters, water monitoring also included sixyal and chemical properties such as pH, temperatur, dissolved oxygen, and turbidity.
