disadvantages of 2.4 GHz wireless module on human body

hi everybody i'm trying to use 2.4G Wireless NRF24L01 PA LNA Board Module that can support 1100 meter distance whit 5db antenna. my question is is that possible to use it in home as switches control all time? does it have disadvantages for human body? what is your comment?
there is some details of this module
Code: 
Overview

The nRF24L01 module is the latest in RF modules from SparkFun. This module uses the 2.4GHz transceiver from Nordic Semiconductor, the nRF24L01+. This transceiver IC operates in the 2.4GHz band and has many new features! Take all the coolness of the nRF2401A and add some extra pipelines, buffers, and an auto-retransmit feature - very nice!

This board features a reverse polarized SMA connector for maximum RF range. And there are PA and LNA circuit on board, with the external antenna it can reach long distance than the one without these parts.

This module comes with the 2.4G antenna (2DB), with 250Kbps transmission rate on open air it can reach the 800-1K meters communication distance.

Note: We now populate these boards with the nRF24L01+. The '+' version of the IC has improved range, sensitivity, and data rates. The command set is backward compatible with the original nRF24L01.
