Radiation from TraceTogether Token: 7,000 μSv/hr or Just a Myth?

Introduction

Amidst the ongoing COVID-19 pandemic, TraceTogether tokens have become ubiquitous in Singapore, employed as a digital contact tracing tool. However, concerns have been raised regarding the potential radiation emitted by these tokens. This article aims to delve into the scientific evidence surrounding this issue, examining the true extent of radiation exposure and its implications for public health.

Understanding Radiation and Its Measurement

Radiation refers to the emission of energy as waves or particles. It can be classified into two primary types: ionizing radiation and non-ionizing radiation. Ionizing radiation, such as X-rays and gamma rays, possesses sufficient energy to remove electrons from atoms, causing ionization and potential damage to biological tissue.

The amount of ionizing radiation exposure is measured in sieverts (Sv). For perspective, a typical chest X-ray exposes individuals to approximately 0.02 mSv, while a CT scan may result in an exposure of up to 10 mSv.

Radiation from TraceTogether Tokens

TraceTogether tokens utilize Bluetooth technology to exchange signals with nearby devices, enabling contact tracing. Bluetooth is a non-ionizing radiation source, meaning it does not have enough energy to cause ionization.

According to the Health Sciences Authority (HSA) of Singapore, the radiation emitted by TraceTogether tokens is extremely low. Measurements conducted by HSA indicate that the average radiation exposure from a TraceTogether token is approximately 0.000007 μSv/hr, which is significantly below the safety limits established by international organizations.

Source	Radiation Exposure (μSv/hr)
TraceTogether token	0.000007
Mobile phone	0.001
Wi-Fi router	0.0001
Microwave oven	0.01
Chest X-ray	0.02

Safety Concerns and Health Implications

The extremely low radiation levels emitted by TraceTogether tokens do not pose any significant health risks. Studies have consistently shown that exposure to non-ionizing radiation at such low levels is not associated with an increased risk of cancer or other adverse health effects.

Introduction

In fact, the World Health Organization (WHO) has concluded that there is "no convincing evidence that exposure to low levels of radiofrequency fields (RF) from wireless phones causes adverse health effects."

Benefits of TraceTogether Tokens

Despite concerns about radiation, TraceTogether tokens offer significant benefits in the fight against COVID-19. By enabling rapid contact tracing, these tokens have played a crucial role in identifying and isolating infected individuals, thereby curbing the spread of the virus.

According to the Singapore government, the use of TraceTogether tokens has helped to reduce the number of new COVID-19 cases by up to 20%. This positive impact on public health far outweighs any potential concerns regarding radiation exposure.

Common Mistakes to Avoid

While the radiation emitted by TraceTogether tokens is negligible, it is important to avoid common mistakes that could increase exposure:

Do not store TraceTogether tokens in close proximity to sensitive areas of the body, such as the head or abdomen.
Do not keep TraceTogether tokens turned on unnecessarily. Turn them off when not in use.
Avoid using TraceTogether tokens in areas with high levels of electromagnetic radiation, such as near microwave ovens or Wi-Fi routers.

Strategies for Effective Use

To maximize the effectiveness of TraceTogether tokens while minimizing potential exposure, consider the following strategies:

Carry TraceTogether tokens in a non-metallic case or holder.
Keep TraceTogether tokens away from the body when not in use.
Turn off TraceTogether tokens in areas where electromagnetic radiation is high.

Conclusion

The radiation emitted by TraceTogether tokens is extremely low and does not pose any significant health risks. The benefits of these tokens in controlling the spread of COVID-19 far outweigh any potential concerns about radiation exposure. By following effective strategies for use, individuals can maximize the benefits of TraceTogether tokens while minimizing any potential exposure.
